Publication number: 20200379405Abstract: An image forming apparatus cartridge includes a coupling member having an axis about which the coupling member is rotatable. The coupling member includes a first end portion operatively connected to a developer roller and a developer supplying roller and a second end portion for receiving a rotational force. The coupling member is movable between a first position in which the axis of the coupling member is substantially parallel to and offset from the axis of the developer roller, a second position in which the axis of the coupling member is inclined with respect to the position of the axis when the coupling member is in the first position, and a third position in which the axis of the coupling member is inclined with respect to the position of the axis when the coupling member is in the first position in a direction opposite to the direction the coupling member is inclined when in the second position.Type: ApplicationFiled: August 19, 2020Publication date: December 3, 2020Inventors: Masanari Morioka, Shiego Miyabe, Takahito Ueno

Patent number: 10788789Abstract: An image forming apparatus cartridge includes a developer roller having an axis L1 and a coupling member having an axis L2. The coupling member includes a first end portion operatively connected to the developer roller, a second end portion, and a connecting portion connecting the first end portion and the second end portion. The image forming apparatus cartridge also includes an urging member that biases the coupling member. The coupling member is movable between a first position in which the axis L2 of the coupling member is substantially parallel to and offset from the axis L1 of the developer roller, and a second position in which the axis L2 of the coupling member is fully inclined with respect to the axis L1 of the developing roller, and the urging member biases the coupling member to the second position.Type: GrantFiled: May 16, 2019Date of Patent: September 29, 2020Assignee: Canon Kabushiki KaishaInventors: Masanari Morioka, Shiego Miyabe, Takahito Ueno
