Patent number: 4916547Abstract: An image forming apparatus of the type producing a single composite color image on a paper which is transported by a belt by transferring image components of different colors to the paper in register with each other. The apparatus reduces with a simple construction the positional deviation of the image components which occurs in an intended direction of paper transport. Recording devices individually adapted for black, cyan, magenta and yellow are arranged side by side. Pattern images for measurement each being associated with a respective one of those colors are formed on the belt. A timing at which each of the pattern images arrives is sensed and counted. The count is compared with a reference value to calculate an amount of deviation. Write start timing signals each being associated with a particular color are generated which are individually variable on the basis of the deviation calculated.Type: GrantFiled: May 26, 1988Date of Patent: April 10, 1990Assignee: Ricoh Company, Ltd.Inventors: Akio Katsumata, Mitsuo Hasebe, Yoshihiro Mitekura, Hiroshi Hosaka, Itaru Matsuda, Kotaro Yonenaga, Takayuki Maruta, Masaaki Kogure
