Abstract:
1. A cartridge comprising: a developer accommodating casing; a rotatable body rotatably provided at the casing and configured to rotate about a rotational axis upon receipt of a driving force, the rotatable body having an outer circumference defining a rotational path during rotation; a pivot member disposed at the rotatable body at a position offset from the rotational axis and configured to pivot about a pivot fulcrum extending in a direction parallel to a tangential direction of the rotational path, the pivot member being pivotably movable between an erect position in which the pivot member erects to form a first angle relative to the rotatable body and a collapsed position in which the pivot member pivots toward the rotatable body to form a second angle smaller than the first angle relative to the rotational body; and a biasing member configured to bias the pivot member toward the erect position.
