Patent number: 7680425Abstract: An image It is formed as a patch image which includes a header image portion Ih of a solid image having a length of a circumferential length of a developing roller or more, and a gradation image portion Ig progressively varied in the tone level thereof from the maximum level to the minimum level. The densities of the patch image on an intermediate transfer belt are sampled. However, the sampling results contain errors resulting from noises or variations and hence, are subjected to a noise removal process, a periodical variation correction process and a reverse correction process. The results detected on the intermediate transfer belt do not always coincide with image densities (OD values) on a recording material. Therefore, the detection results are converted into the OD values, based on which tone characteristics of an apparatus is estimated. Then a tone correction table is updated in a manner to compensate for the tone characteristics.Type: GrantFiled: July 16, 2004Date of Patent: March 16, 2010Assignee: Seiko Epson CorporationInventors: Takashi Hama, Hidetsugu Shimura, Keiichi Taguchi, Hiroshi Nakazato, Ken Ikuma, Hidenori Kin

Patent number: 7536126Abstract: A test pattern P3 longer than a length Ld corresponding to a circumferential length of a developing roller is formed along a moving direction of a photosensitive member (or developing roller). The developing roller transports a great quantity of toner on its surface in a first revolution thereof and hence, the test pattern has a high density. When the residual toner runs low, the toner transport quantity is decreased in the subsequent revolution, so that the test pattern P3 is decreased in the density at its portion beyond the length Ld from its head. If a density difference is observed at place corresponding to a boundary between image portions formed in the first revolution and the second revolution, it is concluded that image quality is degraded due to the shortage of residual toner.Type: GrantFiled: June 9, 2005Date of Patent: May 19, 2009Assignee: Seiko Epson CorporationInventors: Takayuki Kawakami, Takashi Hama, Takatomo Fukumoto, Yoichi Yamada
