Patent number: 11796953Abstract: An image forming apparatus comprises an accommodating unit that accommodates recording materials and has a regulating plate that regulates a trailing edge of the recording material in a feeding direction, detects a recording material fed from the accommodating unit, and measures time from a predetermined timing until a recording material is detected. An information processing apparatus receives time data obtained by a measuring unit from the image forming apparatus, classifies a plurality of time data received from a reception unit into a first group and a second group in accordance with a length of time, and determines using time data included in the first group and the time data included in the second group whether a position of the regulating plate is misaligned in relation to a reference position that corresponds to a size of the recording material accommodated on the accommodating unit.Type: GrantFiled: November 12, 2021Date of Patent: October 24, 2023Assignee: CANON KABUSHIKI KAISHAInventors: Daisuke Momiyama, Takashi Yano, Hidehiro Ushiozu, Masato Suzuki, Tomoki Fujikawa

Publication number: 20230159291Abstract: A sheet feeding apparatus includes a stacking unit including a plate, a feeding unit including a roller, a holder including a detected member, a drive unit and a controller. The detected member is positioned in a first position where the detected member is not detected by a detector in a case that the feeding unit is new, and is moved from the first position to a second position where the detected member is projected so as to be detected by the detector when the new feeding unit is mounted on the holder and the roller is driven. The controller controls the drive unit to perform up-and-down operation of the plate so that the plate is set to a feedable state of the sheet in a case that the feeding unit is mounted, and determines whether or not the feeding unit is new based on a detection result of the detector.Type: ApplicationFiled: November 16, 2022Publication date: May 25, 2023Inventors: Masato Suzuki, Kenichirou Isobe, Eiji Wakiyama, Takashi Yano, Hidehiro Ushiozu

Patent number: 8909073Abstract: A developing unit includes a developer storage unit, a developer bearing member, an agitation member, a flexible member, and a magnet member. The developer storage unit stores a developer. The developer bearing member develops an electrostatic latent image formed on an image bearing member with the developer. The agitation member agitates the developer in the developer storage unit. The flexible member, disposed in the developer storage unit, is distorted by pressure applied by the agitation member via the developer. The magnet member, disposed on the flexible member, is displaced in response to the flexible member being distorted.Type: GrantFiled: July 24, 2012Date of Patent: December 9, 2014Assignee: Canon Kabushiki KaishaInventors: Shinji Hosoya, Toshikazu Tsuchiya, Hidetoshi Hanamoto, Tsutomu Ishida, Taku Fukita, Hidehiro Ushiozu
