<p>PURPOSE:To facilitate operations by providing a first energizing means, a second energizing means, a pressure-releasing member and a pressing member, and pressure-releasing or pressurizing a pressure-roller only by opening/closing an opening/closing unit part. CONSTITUTION:A fixing part 9 is provided with the first energizing means 30, the second energizing means 33, the pressure-releasing member 32 and the pressing member 34. When an image forming device is used while the opening/ closing unit part 18 is closed, the pressure-releasing member 32 is pushed down by the pressing member 34 of the opening/closing unit part 18, the energization of the second energizing means 33 is released, and the pressure roller 25 is energized by the first energizing means 30 and made press-contact with a fixing roller 26. Whereas, when the opening/closing unit part 18 is opened, the pressure- releasing member 32 is not pushed down by the pressing member 34, and the pressure roller 25 is energized against the first energizing means 30 by the second energizing means 33 and separated from the fixing roller 26. Thus, a transfer material can be easily removed only by opening the opening/closing unit.</p> |
