Publication number: 20110311270Abstract: A drum unit is provided. The drum unit includes a frame, a photosensitive drum that is rotatably supported by the frame, a contact member that is held to the frame and that contacts a circumferential surface of the photosensitive drum. The circumferential surface of the photosensitive drum has an image forming area on which an electrostatic latent image is formed and a non-image forming area that is adjacent to the image forming area. The contact member is in surface-contact with the non-image forming area and is not contacting with the image forming area.Type: ApplicationFiled: March 28, 2011Publication date: December 22, 2011Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventors: Takeyuki TAKAGI, Fumio MORITA

Patent number: 7941072Abstract: A cartridge includes; a first gear rotatably provided at the casing; a second gear including a toothed portion and a toothless portion; and a storing portion configured to store the second gear. The second gear includes an arm that is flexible and extends substantially along a peripheral direction of the second gear. An inner peripheral surface of the storing portion includes a bulging portion that bulges inward in a radial direction. The bulging portion has a peak portion closest to a rotation center of the second gear. The arm is deflected while the arm contacts the bulging portion. The deflection of the arm is changed from an increasing tendency to a decreasing tendency at the peak portion as a base point. The toothed portion of the second gear is separated from the first gear when the end portion of the arm has crossed over the peak portion.Type: GrantFiled: June 27, 2008Date of Patent: May 10, 2011Assignee: Brother Kogyo Kabushiki KaishaInventors: Satoru Ishikawa, Takeyuki Takagi, Fumio Morita
