Abstract
An image forming apparatus includes a member arranged in contact with or in proximity to an image carrier, a sensor for measuring an electrical characteristic value of the member, a power supply which switches from a first mode in which one of a constant current and a constant voltage is applied to the member to a second mode in which the other is applied to the member, a storage which stores first correspondence between an amount of use of the member in the first mode and the electrical characteristic value, and a hardware processor. The hardware processor obtains second correspondence between the electrical characteristic value measured with the sensor and the amount of use of the member in the first mode and predicts a serviceable period of the member when the power supply is switched to the second mode based on the first and the second correspondences.
