Abstract

PURPOSE:To prevent wrinkles from being formed at the time of fixing an envelope without any decrease in toner image fixing strength by setting the peripheral speed of a pressure roller below the peripheral speed of a heat roller within a 1-5% range. CONSTITUTION:The toner image fixing device which uses the heat roller 1 and pressure roller 2 drives the pressure roller 2 forcibly to rotate, and the peripheral speed of the pressure roller 2 is set slower than the peripheral speed of the heat roller 1, specially, within a 1-5% range. Consequently, wrinkles formed at the time of envelope fixation are prevented from being formed and sufficient fixation strength is obtained by the fixation.
