Abstract
The object of the present invention is to reduce the burden with regard to cleaning of the test toner pattern formed during AIDC in an electrophotographic image forming apparatus. In order to attain said object, the present invention is an electrophotographic copying machine that transfers a toner image formed on a photoreceptor drum onto a sheet of paper conveyed on a conveyor belt, wherein where the toner density of the test toner pattern formed on the photoreceptor drum under prescribed image formation parameters is optically detected by a sensor, the transfer charger output is set to be lower than it is in image formation mode, and a portion of the test toner pattern is transferred onto the conveyor belt and then wiped off by a cleaner.
