heating device

Abstract

Abstract PURPOSE:To improve the position accuracy of a rotary body driving gear and simplify the constitution of the heating device by pressing a recording material against a heating body across a film by an elastic rotary body and driving the recording material and film at the same time. CONSTITUTION:The elastic rotary body 10 is driven and rotated by a driving source while a member which presses the film 21 is pressed against the heating body 19 across the film 21 and the internal surface of the film 21 is moved at a specific speed in the conveying direction of the recording material while sliding on the surface of the heating body 19. This elastic rotary body 10 is fixed and supported rotatably and the heating body 19 is pressed elastically to reduce a displacing force operating on the film 21. Consequently, the position of the rotary body and the position accuracy of the gear for driving the rotary body are improved, the device constitution is simplified, and the device which is inexpensive and has high reliability is obtained.
