摘要： Disclosed are blades oriented in a trailing configuration for cleaning residual toner from the photosensitive drums of photocopying machines without marring the drum's surface. In one embodiment of the invention, the blade is constructed of layers of resilient material having different moduli of elasticity resulting in the blade's having greater resistance to transverse deformation than to deformation along the primary axis of the blade. In another embodiment, the blade comprises a mass of an elastic material having a partially hollow interior. The hollow interior results in a blade with differing moduli of elasticity in different directions.

摘要： A curved blade overlays the marginal portion of a photocopier drum photosensitive surface at the transfer station to engage copy sheets and direct them to a transport assembly removing the sheets from the transfer station. The blade is pivotally mounted at one end and connected to a reciprocating actuator at the other end. It is pivoted away from its overlaying position, after the transport assembly engages the leading corner of the sheet so that the sheet can then contact the marginal portion, and back to its overlaying position after the trailing edge of the sheet has left the surface of the drum. In one embodiment the actuator is mechanically responsive to the photocopier scanner. In another embodiment, the blade is pivotable about an intermediate portion, and the actuator is operated by a solenoid energizable by a switch at the appropriate times.

摘要： A metering roll, employed between the developing station and the transfer station of a photocopier which uses a liquid toner, controls the thickness of the liquid on the photosensitive drum surface when it is presented to the transfer station. Elements fixed between the drum and roll maintain the central metering portion in a substantially constant spaced apart relationship to the photosensitive drum surface and thereby tend to limit and control the thickness of developer on the drum surface at the transfer station. The elements have different surfaces in sliding, frictional contact with the drum and roll respectively. In one embodiment the elements are strips with opposite parallel surfaces, one in contact with the drum and the other in contact with the roll. In another, the ends of the strip are mounted on reels so that the strip may be moved to vary wear points on the strip if any appear.

摘要： A metering roll, employed between the developing station and the transfer station of a photocopier which uses a liquid toner, controls the thickness of the liquid on the photosensitive drum surface when it is presented to the transfer station. Shoe-like elements fixed between the drum and roll maintain the central metering portion in a substantially constant spaced apart relationship to the photosensitive drum surface and thereby tend to limit and control the thickness of developer on the drum surface at the transfer station. One surface of the element substantially conforms to an arc of the drum surface and another surface defines a hole through which a portion of the metering roll passes.
