ABSTRACT:
An image forming apparatus is provided with a control section which stores detection results of a toner sensor regarding detection patterns. When forming a plurality of detection patterns on an intermediate transfer belt, the control section determines circumference-directional lengths of the detection patterns formed this time, based on the detection results of the toner sensor regarding the detection patterns formed immediately before. Thereby, the waste toner amount and toner consumption are not only decreased but also the time taken to detect the density of a detection pattern is reduced, while maintaining the detecting accuracy thereof.
