  • Publication number: 20140294435
    Abstract: A toner container and system for mounting and/or securing the toner container includes a toner container having a toner dispensing hole, a shutter, a protrusion. The shutter is movable relative to the toner dispensing hole, and is to selectively close the toner dispensing hole. The protrusion is connected to the shutter and movement of the protrusion causes the shutter to move relative to the toner dispensing hole to cover the toner dispensing hole. There is a receiver including a movable catch, the movable catch being in a first position when the toner container is initially inserted into the receiver, and the moveable catch moving to a second position upon insertion of the toner container into the receiver.

  • Patent number: 8805246
    Abstract: A toner replenishing device includes a sub hopper (toner container), a toner detection sensor, an agitator, and a paddle. The sub hopper contains toner. The toner detection sensor is located on a wall surface in the sub hopper and detects whether toner remains at a height at which it is located. The agitator rotates in the sub hopper to clean the detection surface of the toner detection sensor. The paddle serves as a toner collecting unit that collects toner to the vicinity of the detection surface of the toner detection sensor in the sub hopper.
