ABSTRACT:
A color image forming apparatus includes a primary transport system for moving a photosensitive receiving member of continuous length, which is designed to receive the exposure of an original image to be reproduced forming a latent image of the original at an exposure station. The photosensitive receiving member is transported through the exposure station at a maintained constant rate of movement while assuring the transport of the photosensitive receiving member through downstream stations, involving development of the latent image and transfer of the developed image to an image receiving medium, is accomplished without causing slack, wrinkling or jamming of the photosensitive receiving member in the apparatus or distortion of the developed image during its transfer to an image receiving medium. The control of the transport of the photosensitive receiving member through the apparatus may be accomplished with a combination of a primary transport system and a secondary transport system respectively positioned in the region of the pressure transfer section and downstream of the exposure station to transport the photosensitive receiving member at different rates of movement. Conflict due to different transport rates applied to the photosensitive receiving member is eliminated by establishing a differential motion buffer in the transport path between the primary transport system and the secondary transport system. In this connection, the differential motion buffer provides for slack compensation or tension biasing in conjunction with any slack developed in the transport of the photosensitive receiving member through the apparatus.
