- a developer storage portion that stores a developer and has an opening for supplying said developer to outside of said developer storage portion; and
an agitating-and-supplying member rotatably provided in said developer storage portion, said agitating-and-supplying member having a shaft portion and an agitating portion, said agitating portion having a fixed end and a distal end opposite to each other, said fixed end of said agitating portion being fixed to said shaft portion;
wherein said agitating portion has an area corresponding to said opening;
wherein said agitating portion of said area includes a protruding part that protrudes outside of said developer storage portion via said opening;
wherein a length of said distal end of said protruding part of said agitating portion of said area is shorter than a length of a portion of the protruding part shifted from said distal end toward said rotation axis, said length of said distal end and said length of said portion being defined in a direction parallel to a rotation axis of said shaft portion; and
wherein, in said area, a distance between said rotation axis of said shaft portion and said distal end of said agitating portion is longer than a distance between said rotation axis of said shaft portion and an outer wall of said developer storage portion.
