Apparatus for forming color images by the superimposition of visualized latent images having drive means for simultaneously driving at least a recording medium conveying means and a source of black visualized latent images

摘要

Photoreceptor drums for forming color images each have a gear as the drive transmission element at their central shafts. Each gear has an idle gear which in turn is coupled with a first motor via a timing belt. The photoreceptor drum for forming black monochrome images has a gear as the drive transmission element at its central shaft. This gear has an idle gear which is coupled with a second motor.
