Abstract
An exposure apparatus is set to each color so that latent-image lines formed on photosensitive drums,to,have predetermined inclinations from rotation axes of the photosensitive drums,to,to form electrostatic latent images on the photosensitive drums,to,while performing curve correction on the photosensitive drums,to,. Peripheral speeds of the photosensitive drums,to,are controlled so that inclinations of toner images of a plurality of colors on an intermediate transfer belt become equal to each other. Thereby, each pixel is not shifted when light-scanning images are superimposed each other by the exposure apparatus,and it is possible to obtain a high-quality image free from image deterioration due to scanning irregularity caused by inclination shifts of scanning lines,K,,C,,M, and,Y.
