Abstract:
1. A toner cartridge comprising: a main casing accommodating therein toner and formed with an opening which provides communication between an interior and an exterior of the main casing; a shutter movable along the main casing by an external driving force applied in a force direction between a closed position at which the shutter closes the opening and an open position at which the shutter opens the opening; a toner seal formed with a seal opening opposing the opening of the main casing, and interposed between the main casing and the shutter when the shutter is positioned at the closed position; and a guide portion configured to guide a movement of the shutter in an inclined direction inclined with respect to the force direction wherein the main casing has an outer surface extending in a longitudinal direction and has an arcuate shaped portion having an arcuate shape in a cross-section taken along an imaginary plane orthogonal to the longitudinal direction, wherein the outer surface defines a circumferential direction, wherein the force direction is in conformance with the circumferential direction, and the inclined direction is inclined relative to the circumferential direction toward the longitudinal direction, and wherein the shutter moves in the inclined direction along the arcuate shaped portion.
