ヨン検出装置。[Claims for Utility Model Registration] (1) A home position for forming, developing, and transferring an electrostatic latent image on the outer surface of a rotating seamed belt photoreceptor, and detecting the seam of the belt photoreceptor. In a photoconductor unit that detects a mark with a reflective optical sensor, a home position mark is attached to the inner surface of the belt photoconductor, and the home position mark is placed opposite to the path of the home position mark as the belt photoconductor rotates. A belt photoconductor home position detection device characterized by a reflective optical sensor installed inside. (2) An electrostatic latent image is formed, developed, and transferred on the outer surface of the rotating seamed belt photoreceptor, and a reflective optical sensor detects a home position mark for detecting the seam of the belt photoreceptor. A home position detection device for a belt photoreceptor, characterized in that a cleaning pad is brought into sliding contact with a path of the home position mark as the belt photoreceptor rotates.
