Cartridge with member for fixing a member-to-be-energized
A cartridge detachably mountable to a main assembly of an image forming apparatus includes: a frame; a member-to-be-energized; a fixing member, having electroconductivity, for fixing the member-to-be-energized to the frame, wherein the fixing member is electrically connected with the member-to-be-energized; a recessed portion, provided on the frame, where a part of the fixing member enters; and a molded resin portion formed by injecting a melted electroconductive resin material into the recessed portion, wherein when the cartridge is mounted in the main assembly, the molded resin portion electrically connects the fixing member with an energizing portion provided in the main assembly.
1. A cartridge detachably mountable to a main assembly of an image forming apparatus, said cartridge comprising:
a frame;
a member-to-be-energized;
a fixing member, having electroconductivity, for fixing said member-to-be-energized to said frame, wherein said fixing member is electrically connected with said member-to-be-energized;
a recessed portion, provided on said frame, where a part of said fixing member enters; and
a molded resin portion formed by injecting a melted electroconductive resin material into said recessed portion,
wherein when said cartridge is mounted in the main assembly, said molded resin portion electrically connects said fixing member with an energizing portion provided in the main assembly.
2. A cartridge according to claim 1 , wherein said fixing member includes a projection projected into said recessed portion.
3. A cartridge according to claim 2 , wherein said molded resin portion includes an engaging portion engaged with said projection to prevent said fixing member from being detached from said recessed portion.
4. A cartridge according to claim 1 , further comprising a second frame mounted to said frame,
wherein said second frame is provided with an injection port through which the resin material is to be injected.
5. A cartridge according to claim 4 , wherein a contact portion to which said energizing portion is to be contacted is exposed from said injection port.
6. A cartridge according to claim 4 , wherein said second frame is provided with a communication port for connecting said recessed portion and said injection port.
7. A cartridge according to claim 6 , wherein a size of cross section of said communication port perpendicular to an axis of said communication port is smaller in a recessed portion side than in an injection port side with respect to a direction of the axis of said communication port.
8. A cartridge according to claim 1 , further comprising a second frame mounted to said frame,
wherein a contact portion to which said energizing portion is to be contacted is exposed from said second frame.
9. A cartridge according to claim 1 , wherein said member-to-be-energized is a regulating member for regulating an amount of a developer carried on a developer carrying member formed on a photosensitive member.
10. A cartridge according to claim 1 , wherein said member-to-be-energized is a cleaning member for removing the developer from a surface of a photosensitive member.
