ABSTRACT:
A removable cartridge like toning device for electrophotographic imaging apparatus of the type wherein a latent electrostatic image formed on an endless electrophotographic belt is translated past a toning station for rendering the latent image visible. The toning device described is a box-like container for liquid toner having an elongate longitudinal slot formed in the top wall and a feed roller seated for rotation within said container, a portion of the circumferential outer surface of the roller extending from the slot. The side walls of the container are provided with inclined flanges cooperating with conformingly inclined ramps provided in the imaging apparatus at the toning station so that the container is guided to a position closely spaced substantially parallel to the electrophotographic belt. Ring collars are arranged at opposite ends of the roller for free rotation relative thereto, the collars having a slightly greater diameter than that of the roller to define a uniform gap between the roller and the electrophotographic belt when the cartridge is installed. One end of the container carries structure to establish electrical contact with the imaging apparatus while the other opposite end carries a grommet/plunger device cooperable with an upright apertured bracket for locking the container in place once proper orientation is achieved. Installation is effected by sliding the container along the ramps, with operation of the grommet/plunger device bringing the roller into parallel relationship with the electrophotographic belt.
