Abstract
An image forming apparatus includes a photoreceptor, a charger, an exposure device, a developing device, a transfer device, a power supply, a detection element, and a processor. The processor sets a transfer bias used in image forming processing based on the resistance value calculated using the value of the transfer bias supplied by the power supply, a measured value measured by the detection element, and the potential of the photoreceptor estimated from the charging potential at which the charger charges the photoreceptor if the measured value is measured, and determines the state of the photoreceptor based on a change in the surface potential of the photoreceptor if the charger changes the charging potential for charging the photoreceptor.
