Abstract
PURPOSE:To make a high-speed copy possible, by providing a driving control means which rotates and drives an electrostatic latent image carrier for every one copy at a continuous copying time by the length >=2 integer times as long as a unit length. CONSTITUTION:An endless photosensitive belt 1 is provided which has a unit length integer (>=3 integer) times, for example, four times as long as a unit length equal to or longer than length 1a-1e of a unit image surface in the direction of driving, and various means for forming an electrostatic latent image on the belt 1, turning the belt 1, making a toner into an image, transferring the image onto the surface of a transfer paper, and removing the residual toner are provided. A driving control means for a rotation driving means is provided which rotates and drives the belt 1 for every one copy at a continuous copying time by a length >=2 integer (there is no common divisor between this integer and the multiple of the unit length corresponding to the overall length of the belt 1) times, for example, 3 times as long as unit length 1a-1e, and parts of the belt 1 are used in order as shown in table.
