  • Publication number: 20230061068
    Abstract: A biasing force adjusting device includes a roller, a roller holder, a first biasing member, and a second biasing member. The roller faces a mover. The roller holder holds the roller and is displaceable with respect to the mover. The first biasing member applies a first biasing force to the roller holder to press the roller against the mover.

  • Patent number: 11307515
    Abstract: A developing device includes a developer bearer, a developer regulator, a developer supply passage, and a stopper. The developer bearer includes a magnetic field generator and is configured to bear a developer containing toner and magnetic carriers and conveys the developer to a developing area by rotation. A stopper prevents the developer blocked by the developer regulator from moving to a surface of the developer bearer, while securing a supply path for passing the developer in the developer supply passage to the developer bearer between the stopper and an upper end of a side wall of the developer supply passage that is opposite to the developing bearer. A width of the supply path in a direction perpendicular to a direction of a rotation axis of the developer bearer is in a range of 7%-10% of a circumference of an outer diameter of the developing bearer.

  • Patent number: 11169431
    Abstract: The camera side mount is brought, by relative rotation with the accessory side mount, from a first state where each accessory side bayonet claw is inserted between the camera side bayonet claws into a second state where the camera side and accessory side bayonet claws engage with each other. The leaf spring biasing the camera side contact pins in the protruding direction is disposed between the camera side mount and the camera body. When the camera being in the normal position is viewed from the direction facing the camera side mount, the leaf spring extends from both sides of the mount center line, which extends from the center of the camera side mount in the direction of gravity, toward the camera side contact pins. The camera side contact pins are arranged at positions other than a position on the mount center line.
