Patent number: 10061249Abstract: In an image forming apparatus, an image forming unit forms a first image of a first color and a second image of a second color. An obtaining unit obtains information related to relative positions of a first measurement image, which is formed on an image carrier, of the first color and a second measurement image, which is formed on an image carrier, of the second color. A generation unit generates correlation data based on first information corresponding to a first image forming speed and second information corresponding to a second image forming speed. A controller, in a case where the image forming unit forms an image at the second image forming speed, corrects relative positions of the first image and the second image based on the first information in advance and the correlation data.Type: GrantFiled: February 6, 2015Date of Patent: August 28, 2018Assignee: Canon Kabushiki KaishaInventors: Yushi Oka, Shinichi Takata, Hiroshi Matsumoto, Ryou Sakaguchi, Kentaro Tamura, Kazuyuki Iwamoto, Takao Nakajima, Daisuke Aruga

Patent number: 10025250Abstract: An image forming apparatus capable of performing color misregistration correction at image forming speeds while reducing downtime. Image forming units form images of different colors. The formed images are transferred to an intermediate transfer belt. A pattern sensor detects color misregistration amounts of color patterns formed on the intermediate transfer belt. A CPU causes the image forming units to form first color patterns at a first speed and the pattern sensor to detect first color misregistration amounts, and causes the former to form second color patterns at a second speed different from the first speed and the latter to detect second color misregistration amounts. The CPU determines third color misregistration amounts at a third speed based on the first and second color misregistration amounts. The third speed is different from the first and second speeds.Type: GrantFiled: June 22, 2017Date of Patent: July 17, 2018Assignee: CANON KABUSHIKI KAISHAInventors: Kentaro Tamura, Shinichi Takata, Yushi Oka, Hiroshi Matsumoto, Ryou Sakaguchi
