Abstract
A process cartridge collectively accommodates at least a latent image carrier and a developer carrier carrying tonner for visualizing an electrostatic latent image formed on the latent image carrier and includes a side plate unit rotatably supporting the latent image carrier and the developer carrier. The side plate includes a bearing that rotatably supports a rotation shaft of the developer carrier; an elastic body that pushes the bearing against a rotation shaft of the latent image carrier; and a guiding unit that guides the bearing in a direction of the pushing. The guiding unit includes an abrasion preventing structure at a wall surface of the guiding unit that comes in contact with the bearing.
