Abstract
An image forming apparatus characterized by the minimum image deterioration. The surface of a feed roller immediately after a fixing unit is covered with a mold release member to improve the mold release property of molten toner, and cooling means for forcible cooling of a web and a feed roller to improve the coagulation of molten toner, whereby high temperature offset is avoided. Further, a heat insulating member is arranged inside the mold release member of the feed roller, thereby increasing the thermal time constant, ensuring a quick cooling cycle and reducing the thermal expansion of the feed roller.
