Claims

[Scope of utility model registration request]

In an electrophotographic apparatus, the apparatus main body is composed of an upper main body and a lower main body supporting the upper main body so as to be openable and closable, and the shaft of the photoreceptor is inserted into an upward groove provided in the lower main body and assembled. A locking member is provided on the lower body so as to be movable between a locking position where it engages with the photoreceptor and locks the movement of the photoreceptor in the lifting direction, and a retracted position where the engagement is released. an electrophotographic device, wherein the upper body is provided with an elastic member that moves the locking member to the locked position against the urging means when the upper body is closed; Device.
