摘要： A memory medium is provided to a cartridge detachably mountable to an image forming apparatus. Into the memory medium, as information for performing charge control, information on an amount of usage of an image-bearing member and information on a charging alternating voltage (a threshold value for selection control of charging peak-to-peak voltage Vpp) are written. The image forming apparatus includes a charging bias power supply circuit, on its body side, including AC oscillation output means capable of outputting two or more species of alternating peak-to-peak voltages and AC detection means for detecting an alternating current through the image-bearing member. Charge control is performed on the basis of a detected value detected by the AC detection means and memory information for the cartridge, whereby good charge control and space saving and cost reduction of the power supply circuit are compatibly realized.
