  • Patent number: 10466646
    Abstract: A photosensitive drum is rotatable about a first axis extending in a particular direction. A frame rotatably supports the photosensitive drum. A developing roller is rotatable according to driving force about a second axis extending in the particular direction. A surface of the developing roller contacts a surface of the photosensitive drum through toner. A resistance generating member generates a resistance torque TQ1 serving as resistance between the frame and photosensitive drum in a case where the photosensitive drum rotates relative to the frame. In a case where the developing roller rotates according to the driving force in a state where the surface of the developing roller contacts the surface of the photosensitive drum through toner, the resistance torque TQ1 is smaller than a torque TQ2 that causes the photosensitive drum to rotate due to friction between the surface of the developing roller and the surface of the photosensitive drum.
