    摘要: A printing machine and apparatus are disclosed that include an ultrasonically assisted cleaning blade (91) to remove toner particles from an imaging surface. An ultrasonic transducer (102) is attached to the cleaning blade (91) to provide vibrational energy to the cleaning blade. The ultrasonic transducer (102) concentrates vibrational energy at the blade tip for enhanced cleaning. A further element of the present invention is the addition of bias to create a strong electrostatic repulsion between the toner particles and the blade tip causing the toner to explode away from the cleaning edge, and to therefore enhance cleaning.

    摘要: A piezo-active charge retentive member, such as a photoreceptor (1), has a grounded electrode layer (5) separating a photoreceptive layer (7) and a piezo-active layer (3). External vibration sources become unnecessary since supplying an A.C. voltage across the piezo-active layer (3) to the grounded electrode layer (5) causes the piezo-active layer (3), and thus the entire photoreceptor (1), to vibrate. Vibration of the photoreceptor (1) enhances the transfer of development powder from the photoreceptor (1) to the transfer material, such as a sheet of paper. Vibration of the photoreceptor also improves the development of images and assists the cleaning of residual development powder from the photoreceptor surface.

    摘要: An electrically biased cleaning belt brush (110) removes oppositely biased particles from a surface (10). The belt brush (110), which is entrained about supporting members (112,114,116), includes a substrate to which is attached a multiplicity of conductive brush fibers. Electrical biasing means electrically biases the belt brush (110) with alternating regions (181,183) of points and negative polarity. Particles adhering to the conductive fibers are removed from the brush fibers at a detoning station (118).

    摘要: A cleaning apparatus is disclosed for removing residual toner, toner additive films, spots and comets off an imaging surface (10). The toner additives used during development leave more than one layer (20, 30) of toner additive films on the surface (10). An ultrasonic cleaner (80, 81) that has a tip velocity ranging from about 1500 mm/sec to about 3000 mm/sec is used in combination with a blade (50) that has sufficient hardness to remove the thick toner additive films (20) without damaging the surface (10). The vibrational motion of the ultrasonic cleaner reduces friction between the blade (50) and the surface (10) and enables the dislodgment of toner additive films, spots, comets and residual toner from the surface (10).

    摘要: For the enhancement of toner release from an imaging surface on a flexible belt member (10) in an electrophotographic device a resonator suitable for generating vibratory energy is arranged in line contact with the back side of the belt member, to uniformly apply vibratory energy to the member. The resonator includes a horn (152) divided into a linear array of segments (158b), and an array of vibration producing elements (150a), each coupled to at least one horn segment, and driven with a voltage to produce a high frequency vibratory response. To avoid the problem of roll-off in response that occurs at the outer segments of the array of horn segments, the vibration producing elements coupled to the outer horn segments are driven with a higher voltage than those coupled to horn segments in the central portion of the array.
