Abstract

An encoder is connected to the drive system of the optical system of an image forming apparatus including an optical system for exposing a document image to a light and scanning the document image, a home position switch for detecting the optical system when it comes to the vicinity of the starting position, and a resist roller for setting the feeding start timing of a transfer sheet to the transfer section, and, on reproducing the above document image on a transfer sheet, when the pulse signals coming from the encoder, which are counted from the time when the optical system passes through the home position switch, reach the appointed value, the above resist roller operates.
