Abstract
An image forming apparatus includes: a heating unit; a pressure roller; a separation roller whose diameter is smaller than the pressure roller's one; a belt which connects the pressure roller and the separation roller to form a pressure unit, wherein the pressure roller presses the heating unit through the belt to fix a toner image on a sheet of paper passing through a nip between the heating unit and the pressure unit, wherein the separation roller is located such that a direction of the belt from the pressure roller to the separation roller coincides with a tangent to an imaginary circle which the pressure roller forms at the nip or is on a pressure roller side with respect to the tangent.
