Abstract
An image forming apparatus in which there are integrally provided a process cartridge, composed of an image carrying member in which a latent image is formed, and a developing device and/or a cleaning device. The process cartridge is detachably mountable on the apparatus. A moving device moves the process cartridge from a first position, allowing image forming, to a second position in which the process cartridge can be detached. The moving device outputs a signal indicating that the process cartridge is being moved. There is provided a device to output an instruction signal to a controller which, on receipt of the instruction signal, outputs a drive signal to the moving device to move the process cartridge provided that no signal is input from the moving device.
