Abstract
A plurality of photosensitive drums are arranged such that color-separated light images of an original document are formed respectively thereon. The photosensitive drums are independently driven under equal conditions by a single drive source for preventing image colors, i.e., image positions, from being shifted out of registry on an image transfer sheet.
