Abstract
A process cartridge detachably mountable to an image forming apparatus includes a device contributable for forming an image; a developer accommodator; and a sealing member between the image forming device and the developer accommodator, wherein the sealing member is provided by injecting a liquid material which becomes an elastomer when it is solidified.

A process cartridge detachably mountable to a main assembly of an image forming apparatus for forming an image on a recording material using a developer, comprising:
- means for forming an image;
- a developer accommodator;
- and
- a sealing member formed on a connecting surface between said image forming means and said developer accommodator, wherein said sealing member is provided by injecting into a groove formed in the connecting surface a liquid material which becomes an elastomer when it is solidified.
A process cartridge detachably mountable to a main assembly of an image forming apparatus for forming an image on a recording material using a developer, comprising:
- a developer accommodator comprising a plurality of connected members;
- and
- a sealing member provided at a connecting portion between the plurality of members, wherein said sealing member is provided by injecting into a groove formed in the connecting portion a liquid material which becomes an elastomer when it is solidified.
A process cartridge detachably mountable to a main assembly of an image forming apparatus for forming an image on a recording material using a developer, comprising:
- an image bearing member;
- process means actable on said image bearing member;
- a developer accommodator;
- and
- a sealing member forming on a connection surface between said image bearing member and said developer accommodator for preventing leakage of developer from said developer accommodator, wherein said sealing member is provided by injecting into a groove formed in the connection surface a liquid material which becomes an elastomer when it is solidified.
A process cartridge detachably mountable to a main assembly of an image forming apparatus for forming an image on a recording material using a developer, comprising:
- process means;
- developer accommodating means for accommodating the developer;
- a cartridge frame for containing said process means and said developer accommodating means;
- and
- a sealing member formed on a connection surface of said cartridge frame for preventing leakage of the developer from said cartridge, wherein said sealing member is an elastic member provided by solidification of liquid material in a groove formed in the connection surface.
