    • A photoreceptor aluminum alloy substrate is prepared with specific roughness characteristics and an oxide layer for use in multi-layered electrophotographic photoreceptor. A photoreceptor substrate, or drum, is placed in a lathe and turned using a polycrystalline tool to achieve specific roughness characteristics. A oxide layer is then allowed to form on the roughened photoreceptor substrate. The roughened surface of the photoreceptor aluminum alloy substrate in conjunction with the oxide layer on the roughed surface reduces variances in surface energy across the photoreceptor substrate, and eliminates, or greatly reduces, a number of Tiger Stripe and Tiger Tail defects that may occur in an undercoat layer subsequently applied to the roughened photoreceptor substrate. The approach eliminates the need for wet honing and thereby significantly reduces the complexity and cost of fabricating a multi-layered electrophotographic photoreceptor.
    • 制备具有特定粗糙度特性的感光体铝合金基底和用于多层电子照相感光体的氧化物层。 将感光体基材或滚筒放置在车床中并使用多晶工具转动以获得特定的粗糙度特性。 然后在粗糙感光体基底上形成氧化物层。 感光体铝合金基底的粗糙化表面与粗糙表面上的氧化物层结合,减少感光体基底上的表面能的变化,并且消除或大大减少了可能发生在一起的若干虎纹和虎尾缺陷 随后将底涂层施加到粗糙感光体基底上。 该方法消除了对湿珩磨的需要,从而显着降低了制造多层电子照相感光体的复杂性和成本。

    • A method of fabricating a blotter roll for uniformly conditioning liquid images consisting of toner particles and carrier liquid. The method includes electroforming a semi-rigid resilient and perforated metallic substrate for preventing undesirable impressions of substrate outlines and footprints on an image being conditioned. The resilient metallic substrate is electroformed so as to be seamless and to have a cylindrical hollow interior, and first and second open ends. The method next includes forming at least a first absorbent foam layer over the semi-rigid resilient substrate for absorbing carrier liquid from the image being conditioned, and filling the cylindrical hollow interior of the semi-rigid resilient substrate using a porous foam insert for rigidifying the semi-rigid resilient substrate, and for uniformly spreading throughout the hollow interior, vacuum effects on the image being conditioned, of a vacuum source connected to the hollow interior for drawing carrier liquid from the image being conditioned.
