Abstract:
An image forming apparatus, comprising:image forming means for forming a latent image on an image supporting body; developing means for supplying developing agent to the latent image which has been formed by the image forming means; transferring means which contacts with the image supporting body to transfer a developing agent image which has been developed by the developing means to a body on which an image is to be transferred; feeding means for feeding the body between the transferring means and the image supporting body; first driving means for rotationally driving the image supporting body; second driving means for rotationally driving the transferring means; third driving means for rotationally driving the feeding means; first detecting means for detecting the rotating state of the image supporting body; second detecting means for detecting the rotating state of the transferring means; controlling means for determining rotating states of the first and second driving means, and performing control so as stop drive of the first to third driving means when it is detected that rotation of one of the image supporting body and the transferring means is stopped, or it is detected that a difference in rotating speed between the image supporting body and the transferring means is equal to or more than a predetermined value.
