ABSTRACT:
The image forming apparatus according to the present invention detects the amount of remaining toner by using (i) the result of calculation carried out by a toner supply amount calculation section based on an accumulated rotational time measurement section in a region where the amount of remaining toner is not less than a predetermined amount and toner supply is stabilized, (ii) the result of calculation carried out by a pixel count section in a region where the amount of remaining toner gets small and the amount of toner supply gets uneven, and (iii) the result of ATC carried out by a toner density control section. As a result, it is possible to exactly detect the amount of remaining toner without providing a special remaining toner detection device.
