Patent number: 9405218Abstract: An image forming device includes a plurality of developing devices, and a plurality of sloping members disposed in one-to-one correspondence with the plurality of developing devices. Each developing device includes a developer accommodating chamber and a developing roller disposed above the developer accommodating chamber. Each developing device is movable between a first position and a second position lower than the first position in a height direction generally parallel to a vertical direction. Each sloping member has a sloped surface movable in the height direction and a biasing member biasing the sloped surface upward in the height direction. Each sloping member is movable between a third position where the corresponding developing device is placed on the sloped surface and a fourth position where the corresponding developing device is released from being pressed by the sloped surface in a predetermined direction generally perpendicular to the vertical direction.Type: GrantFiled: July 1, 2015Date of Patent: August 2, 2016Assignee: Brother Kogyo Kabushiki KaishaInventors: Yoh Nishimura, Shougo Sato
