Abstract: An improved toner cartridge and contact which pertains to the recycling of the cartridge is disclosed by providing an alternate or additional way of completing the electrical bias connection to the magnetic feed roller by the addition of a simple contact, which is attached to a doctor blade, having a finger extending to ride onto the surface of the magnetic roller. This contact can be attached at either end, or both ends, of the doctor blade thereby connecting the doctor blade to the feed roller, the contact being held in place by the hold-down screws of the doctor blade.

Abstract: A composite seal for preventing leakage of dry toner material from a toner hopper of a toner cartridge is made by interposing a resilient material between two generally smooth elongated rectangular sheets that have slightly different widths. This construction of the seal allows it to be pushed into thin entry slots, but also to expand to fill and seal a pre-existing channel between the toner hopper and the rest of the cartridge. The seal is most advantageously inserted into the cartridge by using a tool formed from two thin sheets of material that have curved ends.
