Abstract
A developing cartridge includes: a flexible developer bag, provided with an opening and provided in a frame, for accommodating a developer; and an acting member contactable to the developer bag. The developer bag is fixed to the frame at its upper portion. The developer bag is swingable by contact with the acting member.
Claims15
A developing cartridge comprising:
- a flexible developer bag, provided with an opening and provided in a frame, for accommodating developer;
- and
- an acting member contactable to said developer bag,
- wherein said developer bag is fixed to said frame at its upper portion, and
- wherein said developer bag is swingable in a direction of the opening by contact with said acting member.
A developing cartridge comprising:
- a flexible developer bag, provided with an opening and provided in a frame, for accommodating developer;
- and
- an acting member contactable to said developer bag,
- wherein said acting member is integrally provided with a contact portion contactable to said developer bag, and
- wherein said contact portion is contacted to said developer bag when said developer bag is swung toward a direction of the opening by contact with said acting member.
A process cartridge detachably mountable to a main assembly of an image forming apparatus, said process cartridge comprising:
- an image bearing member for forming an electrostatic latent image on its surface;
- a frame;
- a flexible developer bag, provided with an opening and provided in said frame, for accommodating developer;
- and
- an acting member contactable to said developer bag,
- wherein said developer bag is fixed to said frame at its upper portion, and
- wherein said developer bag is swingable in a direction of the opening by contact with said acting member.
A process cartridge detachably mountable to a main assembly of an image forming apparatus, said process cartridge comprising:
- an image bearing member for forming an electrostatic latent image on its surface;
- a frame;
- a flexible developer bag, provided with an opening and provided in said frame, for accommodating developer;
- and
- an acting member contactable to said developer bag,
- wherein said acting member is integrally provided with a contact portion contactable to said developer bag, and
- wherein said contact portion is contacted to said developer bag when said developer bag is swung toward a direction of the opening by contact with said acting member.
A developing cartridge comprising:
- a flexible developer bag, provided with an opening and provided in a frame, for accommodating developer;
- and
- an acting member contactable to said developer bag,
- wherein said developer bag is fixed to said frame in a position above the opening with respect to a direction of gravitation when said acting member is driven, and
- wherein said developer bag is swingable in a direction of the opening by contact with said acting member.
