摘要： A process unit includes a rotatable image bearer, an optical writing head to expose the image bearer within an maximum exposure range in an axial direction of the image bearer, a developer bearer, spacers disposed in axial end portions of the image bearer to determine a position of the optical writing head relative to the image bearer and slidingly contact the image bearer, a cleaner disposed downstream from the developer bearer in an image bearer rotation direction, and a remover to slidingly contact the axial end portion of the image bearer to remove a substance adhering thereto. In the axial direction, inner ends of the spacers are positioned inside a toner layer range of the developer bearer extending beyond a largest sheet width. The remover is disposed downstream from the cleaner and crossing a line extending from the inner end of the spacer perpendicularly to the axial direction.

摘要： A developing device includes a toner bearer to rotate while bearing toner and a toner regulator including a bend on a free end side. The bend is disposed in contact with a surface of the toner bearer and defines a regulation nip to adjust an amount of the toner on the toner bearer. The toner regulator further includes an area having a water contact angle greater than or equal to 70 degrees. The area having the water contact angle includes, at least, a downstream end of the bend in a rotation direction of the toner bearer.

摘要： An image forming apparatus includes an apparatus body and a detachable unit to be attached to the apparatus body in an attachment direction and detached from the apparatus body in a detachment direction. The detachable unit includes a rotary body and a unit drive gear. The apparatus body includes an apparatus-body drive gear to engage with the unit drive gear of the detachable unit attached in the apparatus body, at an engageable position on a downstream side of the apparatus-body drive gear in the attachment direction. One or each of the unit drive gear and the apparatus-body drive gear moves to a retracted position at which the one or each of the unit drive gear and the apparatus-body drive gear does not engage with the other of the unit drive gear and the apparatus-body drive gear and does not interfere with attachment and detachment operations of the detachable unit.
