Two part cartridges with force biasing by printer
DC CAFC
First Claim
1. A two part imaging cartridge in which one part is in contact with the other part by at least two guide studs on one of said two parts entering at least two guide channels on the other of said two parts, one of said two parts containing a developer member and the other of said two parts containing a photoconductor, said guide channel being directed to bring said developer member in contact with said photoconductor and having an open end for said entry of said guide stud;
- said two parts having no force biasing member on either part for force biasing said photoconductor against said developer member, force biasing for imaging being dependent upon external force being applied to said two parts;
said part containing a developer member having at least one of said two guide studs.

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.
