Abstract: An image forming apparatus forming an image on a recording material includes an image bearing member; a rotary rotatably provided in a main assembly of the apparatus; a locking member; and a developing cartridge detachably mounted to the rotary, wherein the developing cartridge includes a developer carrying member for developing a latent image formed on the image bearing member, a demountably mounted covering member for covering a surface of the developer carrying member, and an engaging portion which is movable between a first position in which it is projected beyond an outer surface of the covering member to engage with the main assembly locking member when the rotary is rotated in a forward direction which is a direction of rotation during image formation, and a second position in which it is retracted from the outer surface of the covering member.

Abstract: In an image forming apparatus including a rotary member (15) to which a plurality of developing cartridges (B, Y, M, C) (16) are detachably mountable, a user can rotate the rotary member with an easy operation to access the plurality of developing cartridges. A pivotable unit (63) is contactable and separable from a driving train for the rotary member (15). By applying a certain braking force to a pivotal gear (69), the pivotal gear (69) is moved to a position at which the pivotal gear (69) is held in contact with the driving train by a user's operational force. In association with the contact movement of the pivotable unit (63), a solenoid (57) performing a positional control of the rotary member (15) is released.

Abstract: In a rotary-type image forming apparatus, rotation of a rotary is temporarily stopped at a position where a coupling member and a drive transmission member are engageable with each other, and a developing roller is set in a rotating state. Subsequently, the rotary is rotated so as to bring the developing roller into contact with a surface of a photosensitive drum.

Abstract: A color electrophotographic image forming apparatus which simplifies a configuration in which a rotary is rotated to change over respective developing devices to a development position to reduce the costs and save the space, and which simplifies the changeover operation to reduce an operating time. The image forming apparatus sequentially moves and changes over the respective developing devices supported by the rotary to the development position which faces a photosensitive drum by the rotation of the rotary. The rotary is rotated to move the developing devices. A cam is rotated integrally with the rotary, and thereby abutment portions of the cam are abutted against a regulating rotatable member so that the developing devices are spaced from a photosensitive drum. In a state in which the developing devices are abutted against the photosensitive drum, the cam is spaced from the regulating rotatable member by recesses of the cam.

Abstract: An over-stack protective portion is provided on a stopper member. When a sheet feeding device is in a standby position, the over-stack protective portion is held in a position in which the over-stack protective portion is in pressure contact with sheets having the maximum stacking height capable of being fed and supported by a sheet supporting portion. Also, when the sheets are to be fed, the pressure contact of the over-stack protective portion with the sheets having the maximum stacking height is released.

Abstract: A molecular diagnosis system of ovarian cancers encompasses a detection device configured to obtain a detected value of an expression amount of an apolipoprotein A1 gene in ovarian tissue as a diagnosis subject, a storage device configured to store a normal value of the expression amount of the apolipoprotein A1 gene in normal ovarian tissue, and a determination mechanism configured to determine that the ovarian tissue as the diagnosis subject is clear cell adenocarcinoma when the detected value is lower than the normal value.

Abstract: When a shift lever is shifted from an N range to a D range and a predetermined learning condition is established, a learning timer tm_pulse up to a point at which a pulse signal is detected by a primary pulley rotation speed sensor is calculated, and when a deviation between the learning timer tm_pulse and a reference correction amount ?P_offset is larger than a predetermined threshold ?t_pulse_dif, a learned correction amount P_offset is updated.

Abstract: An image heating apparatus includes a contact-sliding member parallel to a generatrix of a heating roller and brought into contact with the heating roller configured to heat a toner image on a recording material. An inlet space and an outlet space are formed at the upstream and downstream ends, respectively, of a contact area. A cleaning member, provided on the downstream side of the contact area, cleans the surface of the heating roller to remove toner and paper dust from the surface of the heating roller.

Abstract: According to embodiments, a heating member or a sliding member arranged in contact with the surface of a fusing roller is moved in an intersecting direction with the rotational direction of the fusing roller in a contact state with the heating member or the sliding member so as to prevent a scratch from being generated on the surface of the fusing roller or to repair the scratch.

Abstract: A color electrophotographic image forming apparatus surely moves and stops each developing device supported by a rotary in a development position without an independent driving motor for rotating the rotary. By the rotation of the rotary, the V number of developing devices supported by the rotary are sequentially replaced and moved to the development position in which the developing device faces a photosensitive drum. A drive transmission mechanism is provided in which each time one of a M number claw portions of a trigger cam is disengaged from and engaged with a solenoid, the trigger cam makes a 1/M revolution, and once every 1/M revolution of the trigger cam, a driving force is transmitted to a rotary gear from a rotary drive gear which is rotated integrally with the trigger cam so that the rotary is stopped after rotated by an angle W which is an aliquot part of (360/V).
