Abstract:
1. A toner cartridge comprising: a first toner accommodating unit having a peripheral surface in which an inner hollow space for accommodating a toner is formed; and an agitating member disposed in the first toner accommodating unit and configured to rotate about a rotational shaft in a rotating direction to agitate the toner, the agitating member having a radial length in a radial direction, wherein the peripheral surface has a wall portion formed with a first supply-hole at an upstream side in the rotating direction, the wall portion being curved about a reference line as a center of curvature and depressed inward of the first toner accommodating unit, the reference line being outside of the first toner accommodating unit in a radial direction of the agitating member and extending in a prescribed direction, the wall portion having a first wall defining one end portion of the first supply-hole and a second wall defining another end portion of the first supply-hole, wherein the first supply-hole penetrates along the rotating direction, and wherein a distance between the first wall and the rotational shaft is larger than a distance between the second wall and the rotational shaft, and is smaller than the radial length of the agitating member.
