Abstract:
An image forming apparatus includes: a photosensitive member; a power supply that applies a bias voltage to the photosensitive member to charge a surface of the photosensitive member; a developer that develops an electrostatic latent image on the photosensitive member; an exposing device that forms the electrostatic latent image on the photosensitive member; a hardware processor; and a memory, wherein the memory stores, in advance, a relationship between a suitable AC voltage at which a discharge amount of AC electric discharge is balanced between positive and negative sides and a current value of a specific AC voltage, and the hardware processor controls the bias voltage in an AC charging type, detects the current value at the specific AC voltage, and determines a setting AC voltage on the basis of the relationship.

Claim (Index 1):
An image forming apparatus comprising:\n a photosensitive member; a power supply that applies a bias voltage to the photosensitive member to charge a surface of the photosensitive member; a developer that develops an electrostatic latent image on the photosensitive member; an exposing device that forms the electrostatic latent image on the photosensitive member; a hardware processor; and a memory, wherein the memory stores, in advance, a relationship between a suitable AC voltage at which a discharge amount of AC electric discharge is balanced between positive and negative sides and a current value of a specific AC voltage set to be equal to or higher than an AC voltage of a discharge start point and be equal to or lower than an AC voltage at which an image defect occurs due to the electric discharge, and the hardware processor controls the bias voltage in an AC charging type, detects the current value at the specific AC voltage, and determines a setting AC voltage on the basis of the relationship stored in the memory.
