An image forming apparatus includes a movable image bearing member; a driver for driving the image bearing member; elements for forming a latent image on the image bearing member; a developing device for developing the latent image formed on the image bearing member by the latent image forming elements; and a transferring device for transferring a developed image developed by the developing device onto an image receptor. The time interval required for the image bearing member to move from a latent image forming position, where the latent image forming elements form the latent image on the image bearing member, to a transfer position, where the transferring device transfers the developed image onto the image receptor, is an integer multiple of a period of the drive non-uniformity inherent in the driver.
