Abstract: A developer unit for developing a latent image recorded on an image receiving member with a supply of particles, the developer unit including a sump for storing a refill supply of particles received from a container for use in the developer unit, the developer unit including a main cartridge body defining a sump portion. A fill aperture is aligned with the sump portion for receiving a toner refill container. A guide member is attached to the main body, the guide member cooperating with a corresponding member in a printing machine to position the main body in the printing machine. A stop member fixed to the guide member so that when the main body is moved in a first direction the stop member positions the main body in a position to be refilled, and when the main body is moved in a second direction, opposed to the first direction the developer unit is in an operative position in the printing machine.

Abstract: A container for delivering a supply of particles for use in a developer unit of an electrophotographic printing machine, the container being fittable to an adapter associated with the developer unit, the container includes a body defining a chamber for storing particles therein, the body defining an aperture in an end thereof and a cover for use in covering the aperture, wherein the cover includes a valve mechanism and a keying feature, wherein the keying feature cooperates with a portion of the developer unit so that upon rotation of the container, the valve mechanism is actuated.
