Abstract
A two part cartridge having a photoconductor part () and a toner part () having no force biasing element on either part. The two parts fit together so that a developer roller () in the toner part contacts a photoconductor drum () in the other part. When the two parts are installed in a printer the cover (), when closed, brings a spring () 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.
