Abstract
An image forming apparatus for forming an image on a recording material includes a main assembly, an image bearing member forming a developer image, a cartridge detachably mountable to the main assembly and including a developing member configured to carry a developer to be applied to the image bearing member, and a transfer unit including an endless belt, a roller supporting the endless belt, and a roller supporting member for supporting the roller. In addition, a developing member moving mechanism moves the developing member relative to the image bearing member between a first position in which the developing member supplies the developer to the image bearing member and a second position which is different from the first position. The developing member moving mechanism is provided between the roller supporting member and the endless belt with respect to a longitudinal direction of the roller.
