Patent number: 9389533Abstract: An image forming apparatus capable of controlling an image forming position with high accuracy. The image forming apparatus has a plurality of image forming sections each including a photosensitive drum and a laser scanner. The laser scanner exposes the photosensitive drum to form an electrostatic latent image thereon. The image forming section develops the electrostatic latent image formed on the photosensitive drum to form a toner image, and the toner image is transferred onto an intermediate transfer belt. A thermistor in the laser scanner detects the internal temperature of the laser scanner. The image forming apparatus controls the image forming sections to form detection patterns on the intermediate transfer belt. An image forming position is corrected based on the temperature detected by the thermistor and a result of measurement of the detection patterns.Type: GrantFiled: April 17, 2015Date of Patent: July 12, 2016Assignee: CANON KABUSHIKI KAISHAInventors: Hiroshi Nakahata, Toshiharu Mamiya, Yuta Okada, Shinichiro Hosoi

Patent number: 8922847Abstract: A plurality of light beams are simultaneously scanned on a surface of a photosensitive member. The surface of the photosensitive member has a curvature factor, and therefore, the light beams have different optical path lengths. Due to differences in the optical path length, a length (scanning width) of a scanning line of one light beam is different from that of another light beam. When a temperature of an optical scanning apparatus increases, the optical path length differences vary, so that differences in magnification between the beams also vary. Therefore, by obtaining correction amounts for the scanning widths depending on the temperature, the light beams are allowed to have substantially the same scanning width even when the temperature of the optical scanning apparatus varies.Type: GrantFiled: April 12, 2013Date of Patent: December 30, 2014Assignee: Canon Kabushiki KaishaInventor: Hiroshi Nakahata
