ABSTRACT:
An image forming apparatus including an image bearing member, an image forming device forming a latent image on the image bearing member and visualizing the latent image; a transfer device transferring the visual image onto a receiving material, using a moving member; a drive controller controlling driving of the image bearing member so that the rotation angular speed of the image bearing member is identical to the targeted rotation angular speed; a pattern detection device detecting pattern images formed on the moving member; and a correction device determining the variation in rotation angle or angular speed per one revolution of the image bearing member on the basis of the detection data and correcting the targeted rotation angular speed by superimposing a correction value to negate the variation in rotation angle or angular speed per one revolution of the image bearing member on the target.
