Abstract
An image forming apparatus includes a mounting portion to and from which a process cartridge including a photosensitive member and a developing roller is attachable and detachable, a separation mechanism that takes a first position to separate the developing roller from the photosensitive member and a second position to bring the developing roller into contact with the photosensitive member, an allowance mechanism that allows the process cartridge with the developing roller kept in contact with the photosensitive member to be mounted on the mounting portion when the separation mechanism is in the first position, an exposure device, and a control unit, wherein, when the developing roller and the photosensitive member are in contact with each other when the separation mechanism is in the first position, the control unit performs an exposure operation while keeping the separation mechanism in the first position during an initial operation of the image forming apparatus.
