Abstract:
An image forming apparatus has a toner cartridge to accommodate toner, a developing unit comprising a developing roller, and a drum unit. The developing unit has a toner supply member supplying the toner to the developing roller, and a frame. The toner supply member has a shaft, and flexible sheets provided at the shaft. The frame has a first chamber accommodating the developing roller, a second chamber next to the first second chamber for accommodating the toner supply member, an inlet opening for introducing the toner from the toner cartridge to the second chamber, and an adjustment member positioned between the first chamber and the second chamber. The adjustment member allows the toner to move from the second chamber to the first chamber when the sheets move from a lower edge to an upper edge of the adjustment member with contacting the adjustment member by rotating the shaft.

Claim (Index 1):
A process unit for use with an image forming apparatus, comprising:\n a drum unit comprising a photosensitive drum; and a developing unit being movable relative to the drum unit, the developing unit comprising:\n a frame comprising:\n a first chamber; \n a second chamber having an inlet opening through which toner is introduced to the second chamber, the second chamber and the first chamber being arrayed in a horizontal direction in a state where the process unit is attached to the image forming apparatus; \n an adjustment member positioned between the first chamber and the second chamber, the adjustment member being configured to adjust movement of the toner between the first chamber and the second chamber; \n a developing roller disposed in the first chamber; and \n a toner supply member disposed in the second chamber, the toner supply member comprising:\n a shaft rotatably supported by the frame, and \n a flexible sheet disposed on the shaft, the flexible sheet being configured to move while being in contact with the adjustment member when the shaft is rotating, \n \n \n wherein the adjustment member has a slit, the slit of the adjustment member having a width ranging from 0.5 mm to 5.0 mm for allowing the toner to pass therethrough from the second chamber to the first chamber.
