Abstract: The present invention provides a component that exhibits a designed thermal response which may be used in an image forming apparatus. The component may include a roller that contacts a heating device such as a fuser.

Abstract: A method of manufacturing an ink jet cartridge comprising, forming a porous core in the shape of a flow passage; placing the porous core in an ink jet cartridge mold; and injecting a molten material around the porous core. An ink jet cartridge for an ink jet printer having a porous core in the shape of a flow passage; an ink jet cartridge body formed by injecting a molten material around the porous core, wherein the ink jet cartridge body comprises a chamber configured to contain ink, and further wherein the porous core is in fluid communication with the ink in the chamber; and a printhead provided on the ink jet cartridge body and including ink ejection nozzles and ink ejectors, wherein the ink ejection nozzles are in fluid communication with the porous core.

Abstract: A method of fabricating a delivery conduit adapted to provide fluid communication between an off-carrier ink source and a printhead, the method comprising the steps of: (a) providing an ink conduit adapted to be in fluid communication with an off-carrier ink source and a printhead; and (b) laminating a fluid barrier layer over the ink conduit to substantially inhibit at least one of permeation of a fluid into the ink conduit from an external environment and permeation of a fluid from the ink conduit to the external environment.
