MULTIPLE PICTURE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent deterioration of picture quality caused by tilt-deviation of a scanning line. SOLUTION: This device has an electrifying means electrifying uniformly surfaces of photosensitive drums 1a-1d, an exposure means 3 in which latent image lines formed on the photosensitive drum 1a-1d by irradiating scanning lines corresponding to picture data of specific colors are arranged so as to have the prescribed tilt for rotary shafts of the photosensitive drums 1a-1d and electrostatic latent images are formed on the photosensitive drums 1a-1d, a developing means 4a-4d developing the electrostatic latent image, and a transcription means superimposing successively and transcribing monochrome pictures formed on the photosensitive drums 1a-1d on an intermediate transcription belt. And rotary speed of the photosensitive drums 1a-1d is controlled so that tilts of transcription lines to which a latent image line (e) extending to a scan finish point E from a scan start point D set at an opposed side to a contact point R with an intermediate transcription belt in the photosensitive drums 1a-1d in the direction of width of the photosensitive drums 1a-1d is developed are made equal.
