Abstract

PURPOSE:To prevent the adhesion of carrier to an electrostatic latent image carrier by detecting the generation of a trouble during the formation of an image and energizing a developing device moving means at the time of generating the trouble to move the developing device from an image forming position to a receding position. CONSTITUTION:The image forming device executes inversional development by means of a two-component developer consisting of toner and carrier and develops an electrostatic latent image carried on the surface of a photosensitive drum 1. When a jam detecting sensor 40 detects the generation of jam during the image formation, a driving system 43 for controlling the driving of the drum 1, a developing sleeve 12, etc., is stopped and a motor 28 is energized. Consequently, a cam plate 27 is rotated and the developing device 5 is moved from the image forming position to the receding position. When the device reaches the receding position, a detecting signal is outputted from a position detecting sensor 33b and the motor 28 is deenergized. Thereby, the carrier is not almost stuck to the surface of the drum 1 and the drum 1 or the blade of a cleaning device 8 can be prevented from damage due to the adhesion of carrier.
