An image forming apparatus including an image receiving sheet transport system in which a photosensitive sheet and an image receiving sheet are pressed together to form an image on the image receiving sheet which is then transported to a glosser unit at a slower speed than the transporting speed of the image receiving sheet by a pressure developing device and the glosser unit, the image receiving sheet being temporarily buckled between the pressure developing device and the transport device, and then being taken up by the glosser unit. The image receiving sheet is smoothly pulled by a one-way clutch in the direction in which it is stretched.

Image forming apparatus

The imaging apparatus which is provided with the image glossing device of the invention has a means for inputting or detecting a type of a receiver sheet. Transferring speed of the receiver sheet through a image glossing device after development process and temperature to which the receiver sheet is to be heated in the image glossing device are determined corresponding to the type of receiver sheet. For a receiver sheet which requires less quantity of heat for glossing, processing time can be reduced by setting relatively high heating temperature and high processing speed. For a receiver sheet which requires much quantity of heat for glossing, satisfactory glossing process can be performed without causing offset and other defects by setting relatively low heating temperature and low processing speed.
