    Abstract: A developing apparatus capable of suppressing an excessive discharge of developer from a developer discharge hole is disclosed. A first opening part through which developer is carried from a first case part to a second case part, and a developer discharge hole through which the developer is discharged are provided to the first case part. A first carrying member includes a counter blade between the first opening part and the developer discharge hole. The counter blade carries the developer in an opposite direction to a carrying direction of a first carrying blade of the first carrying member. A gap is prepared between an upper part of the counter blade and the first case part. A cross-sectional area of a discharge path for the developer from the counter blade to the developer discharge hole changes according to a progress of the developer along the discharge path.

    Abstract: A cartridge detachably attachable to a main body of an image forming apparatus is provided. The cartridge includes a rotary member and a cartridge coupler. The cartridge coupler includes a transmission member coupled to a rotation axis of the rotary member, a receiving member connected to a set coupler provided in the main body for transmission of power, and a connection member connecting the transmission member and the receiving member together. The receiving member has an Oldham structure allowing movement relative to the transmission member in an axial direction. The receiving member is movable to a first position at which a rotation axis of the receiving member is misaligned with a rotation axis of the transmission member in an attachment or detachment direction, and to a second position at which the rotation axis of the receiving member is aligned with the rotation axis of the transmission member.

    Abstract: An image forming apparatus is provided. The image forming apparatus includes a fuser configured to fuse a print sheet on which toner is developed and a fuser driver configured to supply a heating element of the fuser with a power source supplied from an external alternating current (AC) so as to enable the fuser to have a preset target temperature. The fuser driver performs a control of the number of waveforms hours of an AC power source supplied to the heating element by varying a control cycle according to a temperature of the fuser.
