Abstract: An image forming apparatus includes an image carrier unit, a developing device, and an intermediate transfer body. The image forming apparatus body includes a positioning member having a positioning hole for inserting a positioning pin in a mounting direction and a guiding member including a guide rail portion for guiding the image carrier unit when mounting and removing the image carrier unit. The image carrier unit includes a sliding portion that slides with respect to the guide rail portion. When the image carrier unit is drawn from a mounted state where the image carrier unit is mounted to the image forming apparatus body, the sliding portion is drawn by a predetermined distance in parallel with the rotation shaft direction and then moves in a direction where the image carrier retreats from the developing device and the intermediate transfer body, along the guide rail portion.

Abstract: An image forming apparatus includes an apparatus main body, a housing, a photosensitive drum, a cleaning blade, a contact portion, and a contacted portion. The housing and drum are disposed in an internal space of the main body. The blade is a plate-shaped elastic member extending in an axial direction of a rotational axis of the drum, is supported by the housing, and contacts a circumferential surface of the drum for cleaning. The contact portion is disposed opposite the housing in the main body. The contacted portion is disposed at a center portion, in the axial direction, of the housing and is contacted by the contact portion. A position of the center portion, in the axial direction, of the housing is adjusted in a cross section intersecting the axial direction by the housing being inserted into the internal space and the contact portion coming into contact with the contacted portion.

Abstract: An image forming apparatus includes a body, a photoreceptor unit, and a developing unit. The developing unit includes a first attaching/detaching lever that moves a developing sleeve from a first position to a second position by lifting the first attaching/detaching lever. The photoreceptor unit includes a second attaching/detaching lever that moves the developing sleeve from the first position to the second position by lifting the second attaching/detaching lever. The photoreceptor unit and the developing unit move the developing sleeve to the second position by lifting the first or second attaching/detaching lever so that the photoreceptor unit and the developing unit are individually detached from the body.
