  • Developing device, image forming apparatus including developing device, fitting method of coil board to developing device
    Patent number: 9915893
    Abstract: A developing device includes a housing for housing therein a developer containing toner and magnetic carrier, and a first sensor including an oscillation circuit and a coil board which is part of the oscillation circuit and on which a coil pattern is formed. A fitting portion formed by recessing an outer surface of the housing is provided in the housing so as to allow the coil board to be fitted at a position closer to the developer than the outer surface of the housing. The coil board is fitted into the fitting portion.

  • Developing device and image forming apparatus that detect toner density
    Patent number: 9804525
    Abstract: A developing device includes N number of containers, N number of conveying members, N number of first sensors, stirring portions, a switching unit, and a control unit. The N number of conveying members stir and convey respective developers inside the N number of containers. The N number of first sensors are located at the N number of containers to detect toners remaining amount inside of the N number of containers. The stirring portions are located at the respective N number of conveying members to stir the developers at detecting regions opposed to detecting surfaces of the N number of first sensors by rotations of the N number of conveying members. The switching unit selects any one of outputs of the N number of first sensors to output. The control unit receives the selected output to detect the remaining amounts of the developers inside the N number of containers.
