Abstract
Abstract A process kit for use in an image-forming apparatus. The process kit includes a development device, a corona discharger, and a cleaning device disposed in spaced relation around the periphery of a photosensitive drum. Each of the above-mentioned components, including the drum, are releasably mounted in a primary housing which is disposed for insertion into the image-forming apparatus. A bracket is disposed at the opposite ends of the development device, corona discharger, cleaning device, and photosensitive drum to releasably secure these components in the primary housing in a manner which provides access for refurbishment or replacement.

Claim 1
Independent Claim
298 words
A process kit for use in an image-forming apparatus comprising: a primary housing disposed for being removably mounted in said image-forming apparatus in interfacing relation therewith and an inner housing assembly removably mountable in snug-fitting relation in said primary housing, said inner housing assembly comprising: processing means comprising a plurality of processing components including at least a photosensitive drum disposed for having a latent image formed on the surface thereof, a first housing enclosing toner means for co-acting with said surface of said drum for the formation of the latent image thereon, a second housing enclosing a cavity for receiving excess toner from said drum, said first housing, said second housing, and said drum having first and second ends; inner housing assembly support means disposed in releasably secured relation with said first and second housings and said photosensitive drum of said inner housing assembly to provide for removal of said inner housing assembly from said primary housing as a unit, whereby said inner housing assembly may be held away from said primary housing for removal of selected ones of said components from said inner housing assembly subsequent to removal of said primary housing from said image-forming apparatus, said photosensitive drum having first and second shafts, respectively, at said first and second ends thereof, first bracket means having a pair of relatively movable discrete arms provided with distal ends, said arms being rotatably mounted on said first shaft of said photosensitive drum with the distal ends of said arms being pivotally and releasably secured to the respective said first ends of said first and second housings to permit pivotal movement of said first and second housings relative to said drum; and means for releasably securing said first bracket means to said first and second housings and said photosensitive member.
