Abstract

Official abstract text for this publication.

An image formation unit includes a first unit rotatably supporting an image carrier on which an electrostatic latent image is to be formed, and a second unit rotatably supporting a developer carrier configured to develop the electrostatic latent image with a developer. The first unit includes a first engagement portion formed at one end in the direction of the rotational axis of the image carrier, and a second engagement portion provided at a predetermined distance from the first engagement portion at the one end side. The second unit includes a first engaged portion engaged with the first engagement portion, a second engaged portion engaged with the second engagement portion, and a drive input portion provided between the first and second engaged portions and configured to rotate the developer carrier.
