Filed: 1989-04-21
Abstract: PURPOSE:To prevent toner from being offset onto a heat resistant sheet by providing a press-contact member pressing transfer material against the heat resistant sheet downstream of its moving direction while the transfer material is separated from a heating element. CONSTITUTION:The transfer material 12 having an unfixed toner image transferred onto its front surface is carried in the direction shown by the arrow B by a means such as a conveying belt, and smoothly enters the heating element 16 and the nip part of a pressure roller 13. Consequently, the toner image is heated by the heating element 16 via the heat resistant sheet 1, and its front surface is softened and fused. Then, the transfer material is separate from the heating element, enters the press-contact surface of the tape 25 of a pressure plate 24 with the heat resistant sheet 1, is again cooled and solidified without separating from the heat resistant sheet 1, after which it separates from the heat resistant sheet 1. Thus, toner can be fixed without being offset on the heat resistant sheet 1.
