PURPOSE: To prevent the occurrence of uneven printing density due to the deterioration of a photoreceptor caused by ozone produced from an electrifier for applying a high voltage to an image density and to provide high quality color images. CONSTITUTION: This electrophotographic device is provided with a CPU 101 for calculating the driving time of a motor control device 107 after switching off of an electrifier according to the on-time of the electrifier, outputting a motor driving instructing signal S1 and rotating a photoreceptor belt and thus, the partial deterioration of a photoreceptor due to ozone is reduced and color images with always stable printing density is provided without causing uneven printing density at the deteriorated part. |
