Abstract
A toner cartridge is mountable on a process cartridge. The process cartridge includes a supply roller. The toner cartridge includes a first accommodating unit and an agitating member. The first toner accommodating unit has a peripheral surface in which an inner hollow space for accommodating a toner is formed. The agitating member is disposed in the first toner accommodating unit and rotates in a rotating direction to agitate the toner. The peripheral surface has a wall portion formed with a first supply-hole at an upstream side in the rotating direction. The wall portion is curved about a reference line as a center of curvature and depressed inward the first toner accommodating unit. The reference line is outside of the first toner accommodating unit in a radial direction of the agitating member and extending in a prescribed direction.
