Two part cartridges with force biasing by printer
DC CAFCFirst Claim
1. A toner container for use in combination with a photoconductive unit in an image forming apparatus, the toner container comprising:
- a housing including first, second, and third sides, the first side extending between the second and third sides;
a reservoir within the housing that is sized to contain toner;
a developer member rotatably mounted to the housing to receive the toner from the reservoir, the developer member positioned to extend outward from the first side of the housing;
first and second guide members each extending outward from the second side of the housing, the second side being adjacent to the first side; and
a third guide member extending outward from a third side of the housing, the third side being adjacent to the first side;
the reservoir being inlet-free and including an outlet, the developer member being positioned within the outlet.

Abstract
A two part cartridge having a photoconductor part (1) and a toner part (5) having no force biasing element on either part. The two parts fit together so that a developer roller (7) in the toner part contacts a photoconductor drum (3) in the other part. When the two parts are installed in a printer the cover (50), when closed, brings a spring (62) into contact with one side of the toner part while the frame (F) of the printer blocks movement away from the cover. An advantage of the two part cartridge is that the toner part can be replaced without replacing the photoconductor part. Members on the cartridge for force biasing are avoided and the need for training or skill to latch the parts together is avoided.
