Abstract
An image forming apparatus includes a first roller, a second roller, a first voltage applying section, and a control section. An electrostatic latent image is formed on the first roller. The second roller is located opposite to the first roller with a first gap therebetween. The first voltage applying section applies voltage to the second roller. The control section determines a first voltage value to be applied to the second roller during development of the electrostatic latent image. The control section determines a first distance non-uniformity value indicating a degree of non-uniformity of a distance across the first gap. The control section determines a first indicator value by increasing voltage applied to the second roller in stages and performing electrical discharge measurement at each of the stages. The control section determines the first voltage value based on the first distance non-uniformity value and the first indicator value.
