Abstract
An image forming apparatus includes an image bearing member; a scanning device for scanning the image bearing member in accordance with image data; driving source for driving the image bearing member; and a gear for transmitting power to the image bearing member from the driving source. The movement pitch of the image bearing member corresponding to a gear pitch of the gear, and a line pitch of a basic matrix for tone gradation printing are sufficiently different to prevent interference fringe of the image.
