Image reproducing apparatus with high-speed transfer mechanism

摘要

An image reproducing apparatus comprising a driven, toner image retaining member, an intermediate transfer belt, an intermediate transfer belt supporting mechanism including a cylindrical heating roller, and a pressure roller contacting via said intermediate transfer belt in a transfer position with the outer circumferential surface of said heating roller which is in an intermediate transfer belt removing point or a point in the vicinity thereof. The intermediate transfer belt moves in accordance with said toner image retaining member to allow the toner image to be transferred thereto when said intermediate transfer belt is brought into contact with the surface of said toner image retaining member. The intermediate transfer belt supporting mechanism contacts at its outer circumferential surface the rear surface of said intermediate transfer belt. The toner image on said intermediate transfer belt is transferred to a transfer sheet material in the second-mentioned transfer position. The intermediate transfer belt is wrapping more than semi-circle of said heating roller.
