  • Publication number: 20240036494
    Abstract: A developing cartridge includes a housing for accommodating a toner, a developing roller rotatably mounted in the housing, a doctor blade in contact with the developing roller, and a driving device located at a longitudinal end of the housing. The driving device includes a driving force receiving part for receiving a driving force from the outside of the developing cartridge, and is configured to drive the developing roller to rotate. The doctor blade is in contact with a surface of the developing roller to adjust a thickness of a toner layer on the surface of the developing roller. When viewed along a longitudinal direction of the developing cartridge, at least the driving force receiving part does not overlap with the doctor blade. At a moment when the driving force is received by the driving force receiving part, a vibration transmitted to the doctor blade and the developing roller is reduced.
