Abstract
A method for controlling an image forming apparatus is disclosed. An image pattern is developed both by a DC developing process using a developing bias voltage of only a DC voltage and by an AC+DC developing process using a developing bias voltage of a DC voltage overlapped with an AC voltage. The densities of the two developed image patterns is compared with each other to implement toner density control.
