  • Publication number: 20150338796
    Abstract: An image forming apparatus includes: an image forming device; a fixing device; a first feeding path configured to discharge the recording material so that a fixed toner image is directed upwardly; a second feeding path, branching from the first feeding path, configured to discharge the recording material so that the fixed toner image is directed downwardly; a first rotatable member pair, provided in the first feeding path, configured to discharge the recording material; a second rotatable member pair, provided in the second feeding path, configured to discharge the recording material; a first air-blowing mechanism configured to blow air so as to cross the second feeding path when the recording material is discharged using the first feeding path; and a second air-blowing mechanism configured to blow air so as to cross the first feeding path when the recording material is discharged using the second feeding path.

  • Patent number: 9128457
    Abstract: An image forming apparatus includes: an image forming portion which forms a toner image; a collecting container which is detachably arranged in an apparatus main body and which collects toner discharged from the image forming portion; a conveying path which conveys the toner discharged from the image forming portion toward the collecting container, the conveying path being arranged in the apparatus main body to be turnable to a first position positioned during operation of the main body and a second position different from the position positioned in the operation of the main body; and a fixing portion which can fix the conveying path at the first position and the second position.

  • Publication number: 20150164148
    Abstract: The present invention has an object to provide an upper garment that prevents sleeves from dropping and a garment body from unnecessarily largely moving, is less likely to lose its shape, and can provide a comfortable wear feeling, even during strenuous exercise such as sports, particularly, when the arm is raised or rotated. A sleeve peak point 6 of an armhole 5 is located between: a trapezius muscle stop point b1 on a shoulder ridge line L of a wearer in an arm A lowered state; and a trapezius muscle stop point b3 on the shoulder ridge line L of the wearer in an arm A raised state, whereby an arm bending point during arm raising and the armhole 5 coincide with each other. Hence, when the arm A is raised or rotated, sleeves 4 are prevented from dropping, and a garment body is prevented from unnecessarily largely moving.

  • Publication number: 20150139712
    Abstract: An image forming apparatus includes a first feeding path configured to feed the toner collected from an image forming station; a collection container detachably mountable to the image forming apparatus and configured to accommodate the collected toner fed through the first feeding path; and a shutter unit including a second feeding path movably connected with the first feeding path and capable of connecting with the collection container, and a shutter configured to open and close a connecting portion between the second feeding path and the collection container by slide in a direction crossing with the second feeding path in response to mounting and demounting of the collection container.

  • Publication number: 20150093123
    Abstract: An image forming apparatus includes, a unit including at least a photosensitive member and a charging member detachable from a main body of the image forming apparatus, a current detection unit configured to detect a current flowing between the charging member and the photosensitive member, an operation unit configured to be operated by an operator to give an instruction to the image forming apparatus, a display unit provided in the operation unit, and a control unit configured to apply to the charging member a predetermined test voltage having an absolute value greater than a discharge starting voltage based on the instruction from the operation unit, and to perform an operation in a mode for causing the current detection unit to detect a current, wherein the control unit determines, based on the current detected in the mode, whether an error indication is to be given on the display unit.

  • Publication number: 20150078796
    Abstract: An image forming apparatus includes a collection container for collecting toner discharged from an image forming station, the collection container being movable between a mount position in which the collection container is mounted in the apparatus and a removable position in which the collection container is removable from the apparatus; and a door provided on the apparatus to permit access into the apparatus; wherein a track of the collection container when collection container is moved from the mount position to the removable position overlaps a track of the openable member when the openable member is opened and closed, and wherein when the openable member is in the opening position, the collection container is incapable of removing from the main assembly, and when the openable member is in the closing position, the collection container is removable from the main assembly.

  • Publication number: 20130312154
    Abstract: An upper garment having a gusset including three blocks of a flank part, an underarm part, and a sleeve part. The flank part and the sleeve part each have both side edges defined by a gently curved line or a straight line. The underarm part of the gusset includes a front convex part -and a back convex part at both side edges of a front underarm part and a back underarm part, the front convex part -and the back convex part being gradually curved so as to become largest in width in a vicinity of an arm hole bottom. A front body piece, a back body piece, and a sleeve to which the front convex part and the back convex part of the gusset are sewn are configured in different shapes without concaves that are matched with the front convex part and the back convex part of the gusset.

  • Publication number: 20110035859
    Abstract: Patterns for bodies and sleeves are devised to reduce the pull of the bodies from the sleeves when an arm is moved up, down, forward and backward. In an upper garment 1, portions 67 and 87 to be sewn to a first sewing reference position 6 on a front body 2 in a front portion to be sewn 54 in a front sleeve portion 51 project toward the front body 2 relative to a shoulder point SP, and project toward the front body 2 relative to a boundary point 65 between the front portion to be sewn 54 and the first end portion to be sewn 6, and portions 72 and 89 to be sewn to a second sewing reference position 12 on a back body 3 in a back portion to be sewn 55 in a back sleeve portion 52 project toward the back body 3 relative to the shoulder point SP, and project toward the back body 3 relative to a boundary point 70 between the back portion to be sewn 55 and the second end portion to be sewn 12.
