Abstract: In a fixing device, an opposing member contacts a heating member to form a fixing nip between the heating member and the opposing member. A driver rotatively drives at least one of the heating member and the opposing member. A sheet supplier supplies and conveys a sheet to the fixing nip. A recording medium bearing an unfixed toner image is conveyed through a gap between the sheet and the opposing member at the fixing nip with a side of the recording medium bearing the unfixed toner image facing the sheet. At least one of the rotating heating member and the rotating opposing member applies a driving force to the sheet supplied to the fixing nip while the sheet contacts the sheet supplier to apply tension to the sheet at a position upstream from the fixing nip in a sheet conveyance direction.

The flange includes a cylindrical portion that is inserted into an opening portion of the roller at its end. Outer circumference of the cylindrical portion makes contact with inner circumference of the roller, and inner circumference of the flange makes contact with a rotation shaft of the roller. The inner edge of a surface where the flange is in contact with the rotation shaft is located on the inner side of the outer edge of a surface where the cylindrical portion is in contact with the roller in the longitudinal direction of the rotation shaft.

Abstract: An intermediate transfer unit includes a stand member that is integral with an intermediate-transfer-unit body of the intermediate transfer unit. The stand member stretches below the intermediate-transfer-unit body from a trailing edge to a leading edge of the intermediate-transfer-unit in an attachment direction of the intermediate transfer unit.

Abstract: A powder conveying unit conveys powder input from a powder inlet of a powder containing chamber into the powder containing chamber. A powder detecting unit detects a full state of the powder conveyed by the powder conveying unit in the powder containing chamber. A sensor chamber is provided outside the powder containing chamber connected with each other. The powder detecting unit is provided in the sensor chamber, a bottom surface of the sensor chamber is at higher level than a bottom surface of the powder containing chamber, and the bottom surface of the sensor chamber is inclined downward toward the powder containing chamber.

Abstract: A powder housing unit includes a plate-shaped agitating unit that is horizontally arranged inside of a casing to accommodate a powder, a rotating shaft that causes the agitating unit to slide back and forth, and a powder conveying unit that conveys the powder in a horizontal direction during the sliding. The rotating shaft is supported by a shaft supporting unit in a rotatable manner such that a space is formed between the rotating shaft and the shaft supporting unit.

Abstract: A belt unit includes a belt, a contact member, a movable member, an eccentric cam, a contact-separation mechanism, and a braking unit. The contact member is configured to come into contact with the belt. The contact-separation mechanism allows the movable member to move according to the rotation of the eccentric cam to control contact and separation between the contact member and the belt. The braking unit controls the rotation of the eccentric cam by a predetermined angle.

Abstract: When a gloss application sheet is conveyed through a nip formed between a first nip formation member and a second nip formation member pressing against each other, the gloss application sheet is sandwiched between the first nip formation member and a recording medium simultaneously conveyed through the nip. The gloss application sheet includes a first contact surface contacting the first nip formation member and a second contact surface disposed opposite the first contact surface for contacting the recording medium. The first contact surface has a reduced adhesive force compared to the second contact surface.

Abstract: In a fixing device, an opposing member contacts a heating member to form a fixing nip between the heating member and the opposing member. A driver rotatively drives at least one of the heating member and the opposing member. A sheet supplier supplies and conveys a sheet to the fixing nip.

Abstract: An image forming apparatus includes a cover and a supporting unit. The supporting unit includes a holding member, a supporting member, a first biasing unit, and a positioning unit. The holding member holds the transferring member. The supporting member movably supports the holding member, so that the transferring member can move toward or away from a specific member arranged in the main body. The first biasing unit biases the transferring member toward the specific member. When the cover is in a closed state, the transferring member is pressed against the specific member. The positioning unit performs positioning of the supporting member with respect to the main body.
