の定着装置。[Scope of Claim for Utility Model Registration] A clamshell type electronic photograph in which an upper unit having a heating roll and a lower unit having a pressure roll are connected to each other so that they can be opened and closed vertically around a rotating shaft on the paper feed side. In the fixing device of the apparatus, a pressure arm is provided, one end of which is rotatably fixed to the lower unit, and an intermediate part of which presses against the pressure roll or a member attached thereto. A pressure spring is stretched between the rotation support shaft and a position spaced apart from the rotation support shaft, and a stopper stops the rotation of the pressure arm due to the biasing force of the pressure spring midway when the fixing device is opened. A fixing device for an electrophotographic apparatus, characterized in that a member is provided, and the upper unit is further rotated and separated by the residual force of a pressure spring, thereby forming a gap between the pressure roll and the heating roll. Device.
