Patent number: 7876349Abstract: An image forming apparatus includes: a sheet tray; an image forming unit that forms an image on a recording sheet; a sheet transporting path that allows a transportation of the recording sheet fed from the sheet tray to the image forming unit; and a sheet detecting unit that detects a passage of a rear end, with respect to a direction in which the recording sheet is transported, of the recording sheet along the sheet transporting path. The transportation of the recording sheet is temporarily stopped at the time of, or after a predetermined time from when the rear end is detected by the sheet detecting unit. The transportation of the recording sheet is resumed on the basis of data on a size of the transported recording sheet and a timing of image formation by the image forming unit.Type: GrantFiled: January 14, 2009Date of Patent: January 25, 2011Assignee: Fuji Xerox Co., Ltd.Inventors: Koichi Sato, Naohito Otsuki, Hirofumi Katayama, Toshikazu Takubo
