  • Publication number: 20210132537
    Abstract: A sheet conveying apparatus installed in an image forming apparatus according to the present disclosure includes a first guide member provided to a rear cover and configured to guide a sheet along a conveying path, a second guide member provided to the rear cover and configured to be movable between a first position where the sheet is guided to a nip of intermediate discharging rollers and a second position farther from the nip in a sheet conveying direction than the first position, and a movement mechanism configured to move the second member. When the rear cover is moved from a closed position toward an opened position, the movement mechanism moves the second guide member from the first position to the second position.

  • Patent number: 10317816
    Abstract: A developing cartridge is provided. The developing cartridge includes a housing which accommodates developer therein, a receiving member provided which couples with a force output member of an image forming apparatus to receive a driving force, a developing roller which rotates by the driving force received by the receiving member; a detectable rotary member having a first detectable portion and a second detectable portion and rotates by the driving force from a first rotational position where the first detectable portion is detected by a detection member provided in the image forming apparatus to a second rotational position where the second detectable portion is detected by the detection member, and a cut-off mechanism which cuts off a transmission of the driving force from the receiving member to the detectable rotary member in a state where the detectable rotary member is positioned in the second rational position.
