Image forming device with misregistration correction achieved by photo-conductor speed controlled variation of latent image tilt

Abstract

As the speed of a photoconductor drum 1a can be independently varied by providing a rotational speed adjustment mechanism to the photoconductor drum 1a, an inclined angle in a diagonal direction can be varied and as a result, misregistration can be adjusted. Also, exposure device with the inclination of a scanning line with the photoconductor drum 1a provided and control over correcting the inclination of the scanning line on the photoconductor drum 1a is executed by control over varying the peripheral speed of the photoconductor drum 1a. Hereby, a multiple image formation device wherein the configuration of color misregistration correction device is simplified is provided as an image formation device used for the output device of a computer and others.
