ABSTRACT:
An image forming apparatus includes an image forming unit for forming a developer image on a first image bearing member, a transferring unit for transferring the developer image on the first image bearing member onto a second image bearing member, a cleaning member abutted against the first image bearing member, and an abutting pressure changing device for changing the pressure under which the cleaning member is abutted against the first image bearing member, wherein control is carried out such that the abutting pressure in a second operation in which a developer image on the first image bearing member that is not transferred onto the second image bearing member is removed is higher than the abutting pressure in a first operation in which a developer remaining on the first image bearing member is removed after the developer image is transferred onto the second image bearing member.
