Abstract
A cartridge includes: a toner accommodating frame including a toner feeding opening communicating with a toner feeding chamber and a toner filling port; a rotatable member; and a toner seal member. The toner seal member includes a first fixed portion and a second fixed portion which are fixed on the toner accommodating frame at an edge of the toner feeding opening along a longitudinal direction of the toner feeding opening, and includes a third fixed portion fixed on the rotatable member. With rotation of the rotatable member, the first fixed portion of the toner seal member is peeled off from a fixing portion to open the toner feeding opening. The toner is filled into said toner accommodating frame through the toner filling port such that the toner is first filled into a recess defined by said toner seal member.
