摘要： An intermediate transfer unit is attached to a position in the main body portion from a front side of the main body portion along the depth direction in a detachable manner. A cover portion extends in the depth direction and along a region of the outer circumferential surface of a rotating image carrying member that is more on a downstream side in a rotation direction of the image carrying member than the top region of the rotating image carrying member that is in contact with the intermediate transfer belt. A shield portion is provided on a portion of an upper surface of the cover portion that is closer to a front surface of the main body portion than the intermediate transfer belt. The shield portion has a taper surface that is inclined diagonally downward from a top surface of the shield portion toward the intermediate transfer belt.

摘要： An image carrier unit includes an image carrier, a charging device, and a unit housing. The charging device is attachably/detachably held in the unit housing, and electrically charges a surface of the image carrier. The unit housing integrally holds the image carrier and the charging device. The unit housing includes a light shielding member disposed at a first position at which the light shielding member blocks charge elimination light shone onto the image carrier from a charge elimination device provided on a side of the image forming apparatus such that the charge elimination light does not reach the charging device, the first position overlapping with an attachment-detachment path of the charging device. When detaching the charging device from the unit housing, the light shielding member moves from the first position to a second position retracted from the attachment-detachment path of the charging device.

摘要： An image forming apparatus includes a housing; a process cartridge; and a protective member. The process cartridge is detachably attached to the housing and includes a drum unit; and a developing unit. The drum unit includes a photosensitive member. The developing unit includes a developing roller; and a first wall. The developing roller defines a first axis extending in an axial direction and is configured to rotate about the first axix. The first wall has a first surface; and a second surface opposite thereto. The first surface extends in the axial direction and faces the developing roller. The protective member is detachably attached to the process cartridge and includes a spacer. The drum unit includes a second wall. The second wall has a third surface. The third surface extends in the axial direction and faces the second surface. The spacer is disposed between the second surface and the third surface.
