  • Lift mechanism for one or more developer members in an image forming device
    Patent number: 7734226
    Abstract: The present application is directed to devices and methods to position a developer member relative to a photoconductive member in an image forming device. One embodiment includes an elongated lift plate positioned in proximity to a photoconductive member. An elongated opening may be positioned within the lift plate. The opening may include a first section and a second section. The first section may be positioned farther from the photoconductive member than the second section. A positioning member may be positioned within the opening, and be operatively connected to the developer member. A hold down may bias the positioning member towards an edge of the opening. The lift plate may be longitudinally movable between a first position with the positioning member in the first section of the opening that positions the developer member away from the photoconductive member, and a second position with the positioning member in the second section that positions the developer member against the photoconductive member.
