Color image forming device to prevent color shifting

Abstract

Disclosed is a color image forming device in which latent images are formed by radiating a light beam onto a photoreceptor for each of colors, the latent images are developed to provide visible images, and a recording medium is transported to the visible images a plurality of times to form on the recording medium a color image consisting of a plurality of colors. The color image forming device includes a unit for detecting a reference transporting position of the recording medium to be moved to the photoreceptor, a unit for detecting a scan start signal of the light beam, a unit for measuring an error time from detection of the reference transporting position to detection of the scan start signal, and a unit for correcting a radiation timing of the light beam in accordance with the error time.
