Accommodating container, process cartridge and electrophotographic image forming apparatus

A developer container comprising:

• an accommodating chamber for accommodating developer, the accommodating chamber being provided with an opening;
• a seal member for unsealably sealing the opening, the seal member including a slit;
• and
• a rotatable member rotatably supported inside of the accommodating chamber,
• wherein the rotatable member includes a shaft portion and a projection extending in a radial direction of the shaft portion the projection being configured to wind up the seal member when the shaft portion rotates, and
• wherein the slit and the projection are provided in a non-overlapping positional relationship with respect to a longitudinal direction along the shaft portion.

• a seal member for unsealably sealing the opening, the seal member including a hole;
• a rotatable member rotatably supported inside of the accommodating chamber;
• and
• a vibrating sheet provided inside of the developer container,
• wherein the rotatable member includes a shaft portion and a projection extending in a radial direction of the shaft portion, and
• wherein the hole and the projection are provided in a non-overlapping positional relationship with respect to a direction along the shaft portion,
• wherein the seal member includes a connecting portion connected with the rotatable member and an interconnecting portion having the hole, and
• wherein the vibrating sheet is contactable with the interconnecting portion so that the developer is moved toward the opening and passes through the interconnecting portion.
