Process cartridge and image forming apparatus

A process cartridge that 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, the process cartridge comprising:

• a side plate unit rotatably supporting the latent image carrier and the developer carrier, the side plate including a bearing that rotatably supports a rotation shaft of the developer carrier;
• an elastic body that pushes the bearing toward the latent image carrier;
• and
• a guiding unit that guides the bearing in a direction of the pushing, wherein
• the guiding unit includes an abrasion preventing structure at a wall surface of the guiding unit that comes in contact with the bearing, and
• the abrasion preventing structure includes a plate-like member that is detachable to the wall surface and has a surface capable of contacting a peripheral surface of the bearing.
