徴とする画像形成装置。[Scope of Claim for Utility Model Registration] Photoconductor drums that touch one plane at the bottom and are arranged parallel to each other, and a transfer belt that sequentially moves in contact with these photoconductor drums and carries and conveys transfer paper. A color image forming apparatus which transfers toner images of mutually different colors formed on each of the photoreceptor drums in a superimposed manner onto a transfer sheet carried and conveyed by the transfer belt, the color image forming apparatus comprising: One end of the drum is supported by one side plate, the other end is supported by a face plate provided on the other side plate, one of the photoreceptor shafts is used as a reference axis, and the other end of the other photoreceptor drum is supported by a shaft. So that the direction is the axial direction of the reference axis above,
In an image forming apparatus supported by the face plate via a shaft support position adjustment means, the shaft support means for supporting the reference shaft on the face plate is the same as the shaft support position adjustment means for another photoreceptor shaft on the face plate. The shaft support position of the reference shaft is fixed at a predetermined position by reversing one of the parts and assembling it, and by assembling it without reversing the front and back, the shaft support position can be adjusted. An image forming apparatus characterized by:
