Claims

[Scope of utility model registration request]

A pair of photoconductor rollers are supported at both ends of the frame, and by elastically pushing apart the axes of both photoconductor rollers, the loop-shaped band-shaped photoconductor is stretched to cover the frame, and the above-mentioned In a photoreceptor unit in which a frame is housed in an upper cover and a lower cover, the frame is composed of a main frame and a sub-frame that is extendable and contractible with respect to the main frame, and
A spring is attached to one of the above-mentioned double force bars to directly or indirectly contact the support shaft of the photoconductor roller inserted into one frame and bias it in a direction to widen the distance between the axes of both photoconductor rollers. 1. A support device for a band-shaped photoreceptor, characterized in that the device is disposed in a band-shaped photoreceptor.
