PURPOSE:To improve image quality by constituting a pressurizing member on a photosensitive belt which abuts to a developing part with an elastic body. CONSTITUTION:The pressurizing member 9 which raises contact pressure of a mag roll 5a of a developing device 5 to the OPC (organic photo conductor) belt 1 and retains contact area even is attached to be in contact with an inner side of the OPC belt 1, and is constituted of the elastic member. Therefore, the contact area of the OPC belt 1 and the mag roll 5a can be pressurized widely and with an even pressure on the surface of contact. Thus, non developed part becomes small and the image quality is improved. |
