Abstract
An optical image writing unit includes a photoconductive body, a writing device for optically writing images periodically on the photoconductive body at a writing interval t.sub.0, and a driving mechanism, operatively coupled to the writing means, for moving the photoconductive body so that the images are periodically written by the writing device at a predetermined area on the photoconductive body. The driving mechanism includes a driving motor, and a driving pulley rotated by the driving motor so that the photoconductive body is moved by rotation of the driving pulley, wherein the driving mechanism is formed so that a time in which the driving pulley makes one revolution is approximately one n-th of the writing interval t.sub.0, n being an integer.
