A receptacle for particulate matter to be supplied to a reproduction apparatus. The receptacle includes a container, adapted to store particulate matter, has an opening defined therein. A flange is located about the defined opening so as to facilitate placement and removal of the receptacle with the reproduction apparatus. A breathable seal member is provided having a body portion and a readily accessible end portion. The body portion is bonded to the flange for covering the defined opening. The bond is particularly formed in a pattern of repeating minimum and maximum distances from the defined opening to reduce the forces required to break the bond and remove the breathable seal from the flange.

A receptacle for particulate matter to be supplied to a reproduction apparatus. The receptacle includes a container adapted to store particulate matter. The container has an opening defined therein, and a flange located about the defined opening so as to facilitate placement and removal of the receptacle with the reproduction apparatus. A slide cover is supported by the flange for selective movement to a first position covering the defined opening and a second position uncovering the defined opening. The slide cover is releasably secured to the container in an out of the way location when the slide cover is in the second position.

An improved electrophotographic toning station for use in an electrophotographic printer includes a unitary bearing cap and tension sprocket assembly that allows for the use an intermediate drive chain to drive a primary drive sprocket that drives the toning shell at high speed, through a primary drive chain. A unitary bearing cap and tension sprocket assembly that allows the tension sprocket assembly to be properly located relative to the intermediate and primary drive sprockets, such that the components of the toning station may be adjusted relative to each other without interference from the tension sprocket assembly.
