Claims

[Scope of Claim for Utility Model Registration] Collars with a diameter slightly larger than that of the magnet roller are provided at both ends of the magnet roller, and a developing tank that can be pulled out in the axial direction and removed is swingably attached, and In a developing device that secures a developing gap corresponding to the difference in radius between the collar and the magnet roller by pressing the collar against the surface of both ends of the photoconductor, a driven part is provided in the developer tank, and a driven part is provided for the development tank. A developing device for electrophotography, comprising a cam that presses a driven part during rotation to move the developing tank away from the photoreceptor.
