Patent number: 8514256Abstract: The quality of an image recorded on electronic paper is improved. Specifically, electronic paper for displaying an image is supplied in a region in which an electric field is generated in the thickness direction of the electronic paper, the electronic paper having charged color particles and being used for displaying an image as a result of charged color particles migrating in the thickness direction. Voltage for generating an electric field in the region is controlled by a voltage control section so that the value of the voltage varies together with time. The quality of an image recorded on electronic paper can thereby be improved.Type: GrantFiled: February 3, 2011Date of Patent: August 20, 2013Assignee: Seiko Epson CorporationInventors: Satoshi Ogawa, Shinichi Kamoshida, Shigekazu Yanagisawa, Takashi Nitta, Yoshiteru Nishimura, Katsuhito Gomi

Publication number: 20110076067Abstract: A fixing apparatus for forming an image on a transfer material includes first and second fixing roller units, a suction guide, and a movement member. The first fixing roller unit includes a first heating roller that heats the transfer material bearing the image and a first pressure roller being in contact with the first heating roller. The suction guide guides the transfer material, and includes a suction surface that vertically upwardly sucks the transfer material after being heated by the first fixing roller unit. The second fixing roller unit fixes the transfer material after being guided by the suction guide, and includes a second heating roller heating the transfer material and a second pressure roller being in contact with the second heating roller. The second pressure roller is disposed above the second heating roller in the vertical direction. The movement member causes the second pressure roller to move vertically upwardly.Type: ApplicationFiled: September 16, 2010Publication date: March 31, 2011Applicant: SEIKO EPSON CORPORATIONInventors: Yoshiyuki NAGAI, Kenjiro YOSHIOKA, Katsuhito GOMI
