Abstract
An image forming apparatus has at least one image carrier, a device for forming a latent image on the image carrier at a latent image forming position, a device for developing the latent image on the image carrier at a developing position, and a device for transferring the developed image on the image carrier onto an image receiving member. The apparatus features a drive source, and image carrier pulley connected to each of the at least one image carriers, a drive pulley connected to the drive source, and a device for transmitting a driving force from the drive pulley to each image carrier pulley. The time taken to rotate each of the at least one image carriers from the image forming position to the transfer position is substantially equal to an integer multiple of the time taken to make one revolution of the drive pulley.
