摘要： PROBLEM TO BE SOLVED: To obtain an image forming apparatus that can correct distortion of an image caused by bending of a photoreceptor drum with simple constitution, and then obtain a high-quality image whose color shift is inconspicuous.
SOLUTION: In the image forming apparatus, photoreceptor drums 10y, 10m and 10c having a comparatively small outside diameter, and a photoreceptor drum 10k having a comparatively large outside diameter are juxtaposed. By scanning an outer circumferential surface of each photoreceptor drum with a light beam by a light beam scanning device 30, an image is plotted. Image data inputted in a controller of the light beam scanning device 30 is corrected so as to be linear in a transfer part B on the basis of the image distortion caused by bending of the photoreceptor drums 10y, 10m and 10c in a correction circuit.
