Abstract
An image forming apparatus includes a photoconductor on which an electrostatic latent image is formed by irradiation of the photoconductor with light, a charger, a developing device, a transfer device, a charge removal execution determiner, and a power supply controller. The charger receives a superimposed voltage of a DC voltage and an AC voltage to charge the photoconductor. The developing device develops the electrostatic latent image on the photoconductor into a toner image. The transfer device transfers the developed toner image to a recording medium. The charge removal execution determiner issues a charge removal command when a flow of electric charge from the transfer device into the photoconductor has occurred in an image forming outputting operation. The power supply controller applies only the AC voltage to the charger for a predetermined period in a state in which the photoconductor is rotated, when the charge removal command is issued.
