Abstract
In a color copying apparatus including a plurality of photosensitive members and a mounting table driven by a pulley, in which an original mounted on the mounting table is illuminated to expose the respective photosensitive members with reflected light from the original to thereby form latent images thereon while the mounting table travels and these images, after developed, are transferred overlappingly onto a transfer paper to produce a color copy, a distance between exposing positions for adjacent photosensitive members is an integer multiple of a peripheral length of the pulley.
