  • Patent number: 10429795
    Abstract: An image forming apparatus operable in conjunction with a cartridge having a memory and a terminal, which is electrically connected with the memory and arranged on a downward face of the cartridge, is provided. The image forming apparatus includes a housing having an opening, a controller, and a supporter to support the cartridge at an attachment position. The supporter includes a guiding portion to guide the cartridge there-along and a memory electrode electrically connected with the controller. The guiding portion guides the cartridge being attached to the attachment position to descend as the cartridge approaches from the opening to the attachment position. The memory electrode protrudes upward at a position lower than the terminal on the cartridge and has a height to contact the terminal to electrically connect the controller with the memory when the cartridge is at the attachment position.

  • Publication number: 20190258190
    Abstract: A developing cartridge includes: a casing; a first gear; a second gear; a cover; a link; and an urging member engaging with the second gear and the link. The second gear is rotatable from a first position to a second position in accordance with the first gear when the second gear engages with the first gear. The link is movable together with rotation of the second gear and pivotally movable relative to the second gear. The link has: a first state where a distal end portion of the link contacts the cover; and a second state where the link pivotally moves relative to the second gear. The first state is provided due to resilient deformation of the urging member in the first position of the second gear. The second state is provided due to a restoring force of the urging member in the second position of the second gear.
