Patent number: 7848670Abstract: A developing device includes an image carrier, a developer carrier, a biasing unit disposed upstream of a developing area, and a controller configured to control the biasing unit, and a cleaning member disposed downstream of the developing area to remove the liquid developing agent remaining on the developer carrier. A latent image held on the image carrier may be developed with the liquid developing agent, including charged toner and a carrier liquid, at the developing area where the developer carrier faces the image carrier. The controller causes the biasing unit to apply a first bias voltage to the surface of the liquid developing agent held on the developer carrier during developing, or a second bias voltage thereto during cleaning.Type: GrantFiled: August 17, 2007Date of Patent: December 7, 2010Assignee: Brother Kogyo Kabushiki KaishaInventor: Keisuke Takahashi

Publication number: 20100166462Abstract: An image forming apparatus includes: a plurality of photosensitive members, an endless belt, and a separation mechanism. The photosensitive members are arranged in parallel with and spaced from one another and correspond to respective colors. The plurality of photosensitive members includes a first photosensitive member and at least one second photosensitive member. Each of the photosensitive members has a first end portion and second end portion that is opposite to the first end portion in a longitudinal direction of each of the photosensitive members. The endless belt contacts the photosensitive members. The separation mechanism is configured to swing the second photosensitive member around the first end portion of the second photosensitive member as a fulcrum between a contact position at which the second photosensitive member contacts the endless belt and a separated position at which the second photosensitive member is separated from the endless belt.Type: ApplicationFiled: December 28, 2009Publication date: July 1, 2010Applicant: Brother Kogyo Kabushiki KaishaInventor: Hiroshi Igarashi

Patent number: 7447465Abstract: A multi-function peripheral includes an image forming unit having an image forming device, and an image reading unit having an image reading device and located above the image forming unit. The image forming device forms an image on a recording sheet with moving a carriage reciprocally in a predetermined horizontal direction. The image reading device reads an image of an object by moving an image capturing element in the predetermined horizontal direction when the image forming unit operates. Spring elements are provided between the image forming unit and the image reading unit to apply an urging force therebetween in a direction parallel to the predetermined horizontal direction. The spring elements satisfy the following condition: f f n > 2 , where, f and fn are characteristic frequencies of the image forming unit and the image reading unit, respectively, in the predetermined horizontal direction.Type: GrantFiled: December 23, 2002Date of Patent: November 4, 2008Assignee: Brother Kogyo Kabushiki KaishaInventor: Kan Ishikawa
