Abstract

An image forming apparatus (100A to 100C) includes an image carrier; an image forming unit; a processor (37) for controlling the image forming unit according to a predetermined image forming condition setting data; an image density sensor (30); a reference rotary position detector (18, 71); an image density fluctuation data acquisition unit to obtain an image density fluctuation data of more than one circumferential length of the rotary member (2, 5) with reference to the reference rotary position detected by the reference rotary position detector based on the toner pattern formed on the image carrier detected by the image density sensor; and a correction data generator to generate a correction data to correct a reference image forming condition setting data with a correction amount corresponding to each rotary position of the rotary member (2, 5Ya, 5Ma, 5Ca, 5Ka) to thus reduce the image density fluctuation.
