有する複写機。[Claim for Utility Model Registration] A light beam is irradiated from an optical system light source to the document on the document table, and the reflected light is received by an optical sensor to detect the image density, and the light intensity of the light source or the development process is determined according to the image density. In a copying machine having an automatic toner density adjustment function that automatically sets toner density on a photoreceptor by controlling bias, etc., at least the above-mentioned amount of light is applied between the vicinity of the scanning start position of the optical system light source on the document table surface and the leading edge position of the document. A copying machine that has an automatic toner density adjustment function that includes a medium density surface in a range corresponding to the detection area by an optical sensor.
