摘要：To provide a color image forming apparatus that can implement high speedprinting and produce high quality images free from displacements caused when colortoner images are superimposed one upon another. A color image forming apparatususing an intermediate transfer belt 106. The apparatus is constructed so that a cleaningblade 1191 and a drive roller 115 are arranged so as to confront the intermediatetransfer belt 106 in order that a displacement caused when one color toner image issuperimposed upon another can be controlled within a single image- recording dotduring a primary transfer process. The apparatus is constructed such that la/l < ld·E·t/(L0·&mgr; ·n), where la (m) is the length of the intermediate transfer belt from a driveroller to a cleaning device, l (m) is the total length of the transfer belt, ld (m) is a pitchbetween dots developed on the latent image carrying body, E (kg/m.sup.2) is the Young'smodulus of the transfer belt, t (m) is the thickness of the belt, L0 (m) is the length of arecording medium, &mgr; is the frictional coefficient between the cleaning device and thetransfer belt, and n (kg/m) is the line pressure of the cleaning means in contact with thetransfer belt.
