Abstract

An image forming apparatus includes: a cartridge detachably attachable to the image forming apparatus, the cartridge including an image bearing member and a cleaning member which abuts against the image bearing member to remove a remained developer on the image bearing member; an inputting portion into which information for taking out the cartridge from the image forming apparatus is inputted; and an execution portion capable of executing, after an operation of forming an image on a recording material is finished, an operation of rotating the image bearing member in a direction reverse to a rotation direction of the image bearing member and an second operation of rotating the image bearing member in the rotation direction of the image bearing member when the information is inputted to the inputting portion.

First claim

What is claimed is:

1 . An image forming apparatus comprising:
a cartridge detachably attachable to the image forming apparatus, the cartridge including an image bearing member and a cleaning member which abuts against the image bearing member to remove a remained developer on the image bearing member after a toner image formed on the image bearing member is transferred to a transferred material; an inputting portion into which information for taking out the cartridge from the image forming apparatus is inputted; and an execution portion capable of executing a first operation of rotating the image bearing member in a direction reverse to a rotation direction of the image bearing member after an operation of forming an image is finished and a second operation of rotating the image bearing member in the rotation direction of the image bearing member when the information is inputted to the inputting portion.

2 . The image forming apparatus according to claim 1 ,
wherein the apparatus body includes a primary transfer portion which transfers a developer image on a surface of the image bearing member to an intermediate transfer member or a recording material, and the execution portion operates the second operation such that a movement amount of the imagebearing member by the second operation is larger than a first peripheral face distance on a peripheral face of the image bearing member between a transfer facing position which faces the primary transfer portion and a cleaning facing position which faces the cleaning portion.

3 . The image forming apparatus according to claim 2 ,
wherein the second operation is executed after the execution portion stops rotation of the image bearing member and separates the image bearing member from the primary transfer portion.

4 . The image forming apparatus according to claim 1 ,
wherein the apparatus body includes a primary transfer portion which transfers a developer image on a surface of the image bearing member to an intermediate transfer member or a recording material, the cartridge includes a charging portion which uniformly charges the surface of the image bearing member and a development portion which develops an electrostatic image on the surface of the image bearing member with a developer to form a developer image, and the execution portion operates the first operation such that a movement of the image bearing member by the first operation is smaller than at least either a first peripheral face distance on a peripheral face of the image bearing member between a transfer facing position which faces a primary transfer portion and a cleaning facing position which faces the cleaning portion or a second peripheral face distance on the peripheral face of the image bearing member between a charging facing position which faces a charging portion and a development facing position which faces a development portion.
