Abstract
An image forming apparatus includes a photoreceptor, a charging unit, an exposure unit, a developing unit, a transfer unit, a detector, and a controller. The charging unit charges the photoreceptor. The exposure unit exposes the photoreceptor charged by the charging unit to light and forms an electrostatic latent image on the photoreceptor. The developing unit develops the electrostatic latent image that has been exposed by the exposure unit and formed on the photoreceptor. The transfer unit transfers an image obtained by development by the developing unit to a transfer object. The detector detects strip developer, which is a strip-shaped developer image formed on the transfer object. The controller controls at least one of the charging unit, the exposure unit, the developing unit, and the transfer unit, based on a length of the strip developer in a conveying direction detected by the detector, such that timings for varying potentials of the photoreceptor and the developing unit in a same direction are equal to each other.
