摘要： A contactless process for detecting electrical patterns on the outer surface of a member comprising providing a member having a charge pattern on an outer surface, repetitively measuring the charge pattern on the outer surface of the member with an electrostatic voltmeter probe maintained at a substantially constant distance from the surface, the distance between the probe and the imaging member being slightly greater than the minimum distance at which Paschen breakdown will occur to form a parallel plate capacitor with a gas between the probe and the surface, the frequency of repetition being selected to cause all time dependent signals to fall out of phase by a predetermined amount, and averaging the out of phase time dependent signals over a sufficient number of measuring repetitions to eliminate the time dependent signals. In one embodiment, the contactless process detects surface potential charge patterns in an electrostatographic imaging member. Apparatus for carrying out these processes are also described.

摘要： By varying corona producing element height/projection, a more uniform charge potential is achieved. Elements, such as pins or teeth, are shorter at the edges of an element array and grow longer as one moves toward the center of the array. Such variation in height/projection overcomes shielding from adjacent teeth, as well as other effects, to yield the more uniform charging potential.

摘要： The present invention is a charging apparatus capable of electrically tuning or altering, on a relatively local scale, the corona ion current passing between a corona producing device and a charge retentive surface. The charging apparatus, which may be either a corotron or a scorotron, is specifically adapted to apply a uniform charge to a charge retentive surface which characteristically exhibits non-uniform charging behavior. More specifically, the charging apparatus comprises corona producing devices, spaced apart from the charge retentive surface, for emitting a corona ion current, and device, responsive to a bias voltage, for locally altering the corona ion current passing between said corona producing device and the charge retentive surface. In the described embodiments, the ion current altering device includes segmented grids, segmented shields and segmented electrodes, all of which may be maintained at variable bias voltages to produce local variation in the ion current passing to the charge retentive surface.

摘要： A flexible imaging sheet and a method of constructing a flexible imaging sheet is disclosed. The method of constructing a flexible imaging sheet comprises a step of overlapping, a step of joining, and a step of shaping. In the step of overlapping, a first marginal end region and a second marginal end region of a sheet are overlapped to form an overlap region and a non-overlap region. In the step of joining, the first marginal end region and the second marginal end region of the sheet are joined to one another by a seam in the overlap region. In the step of shaping, the overlap region is shaped to form a generally planar surface co-planar with a surface of the non-overlap region. The flexible imaging sheet comprises a first marginal end region and a second marginal end region The first marginal end region and the second marginal end region are secured by a seam to one another in the overlap region. The first marginal end region and the second marginal end region are substantially co-planar to minimize stress on the flexible imaging sheet. Minimization of stress concentration, resulting from dynamic bending of the flexible imaging sheet during cycling over a roller within an electrophotographic imaging apparatus, is particularly accomplished in the present invention.

摘要： A belt loading apparatus has been provided for loading a flimsy continuous belt onto a belt support and drive assembly including a vertical front end having a first shape and without damage to the belt. The belt loading apparatus includes a wall member defining a sleeve including an outer surface having a total outer surface area, a first edge and a second and opposite edge. The second edge has a vertical profile having a second shape such that the second shape of the second edge is a mirror image of the first shape of the belt support and drive assembly. The belt loading apparatus then includes friction reducing members formed on the outer surface of the sleeve for temporarily supporting and spacing a flimsy continuous belt to be loaded onto the belt support and drive assembly. The friction reducing members each have a belt contact area such that a sum total of belt contact areas of all the friction reducing members is significantly less than the total outer surface area of the sleeve.
