Toner Cartridge Having Linearly Movable Shutter Member

Abstract

A developer cartridge includes a casing, a shutter member and a screw auger. The casing is configured to accommodate developer therein, the casing extending in a first direction and being formed with an opening. The shutter member is configured to be linearly movable between an open position and a closed position in the first direction, the shutter member opening the opening at the open position to permit the developer to flow out from the casing and closing the opening at the closed position to prevent the developer from flowing out from the casing. The screw auger extends in the first direction and is configured to convey the developer toward the opening, the screw auger being linearly movable in the first direction in conjunction with the movement of the shutter member.

Dependencies are inferred from the claim text.
