    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 electrophotographic device of the type including a flexible belt charge retentive member (10), driven along an endless path through a series of processing stations that create a latent image on the charge retentive surface, develop the image with toner, and bring a sheet of paper or other transfer member into intimate contact with the charge retentive surface at a transfer station (D) for electrostatic transfer of toner from the charge retentive surface to the sheet. For the enhancement of toner release from a surface at any of the processing stations, a resonator (152) suitable for generating vibratory energy is arranged in line contact with the back side of the charge retentive surface (10), to uniformly apply vibratory energy to the charge retentive member. The resonator comprises a horn (156), a continuous support member (154), and a continuous vibration producing member (150) that drives the horn at a resonant frequency to apply vibratory energy to the belt. The horn includes a platform or base portion (156), a horn portion (158) extending therefrom, and having a contacting tip (159). The horn is segmented, through the contacting tip to the platform portion, into a plurality of elements which each act more or less individually. In alternative embodiments, the vibration producing member that drives the horn, and/or the support member may also be segmented in a corresponding manner.

    摘要: A resonator (100) for generating vibratory energy is arranged in line contact with a charge-retentive member (10) bearing an image on a surface thereof, in an electrophotographic device, to apply vibratory energy uniformly to the charge-retentive member. The resonator comprises a suction device ( 162), a suction hron ( 158), and an air-tight seal arrangement. When the vibratory energy is to be applied to the charge-retentive surface, suction is applied at the line of contact of the horn with the surface, to draw the surface into intimate engagement with the horn. The invention has application to a transfer station, for enhancing electrostatic transfer of toner from the charge-retentive surface to a copy sheet, and to a cleaning station, where mechanical vibration of the surface will improve the release of residual toner remaining after transfer.

    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.

    摘要: In order to remove toner deposited on a rotating drum (2) in a xerographic copying machine, a blade (18) is positioned with its scraping edge (25) closely adjacent to a surface of the drum (2). Vibrations are imparted to the blade so as to bring the scraping edge (25) alternately into and out of contact with the surface of the drum (2) at short time intervals.
