Title:
【発明の名称】2色コピーの成作方法および電子写真複写機
Document Type and Number:
Japanese Patent JP2735327
Kind Code:
B2
Abstract:
A reproduction device forms a two-color copy in a single-pass mode. An original document (30), bearing fluorescent material on selected portions thereof, is illuminated by a light source (39). The light reflected from the document is transmitted through an colored filter (45) and is projected onto the surface of a monopolar photoreceptor (12). Light incident on the fluorescent material is absorbed over a specific wavelength range and is re-emitted at a different wavelength range. This light, and light reflected from the white background, are transmitted through the filter of a color associated with the re-emitted radiation. Light reaching the photoreceptor discharges charged areas thereon at two energy levels. The resulting latent image incorporates three separate discharge levels, corresponding to the dark image information, colored fluorescent areas, and background areas. The dark and colored areas are developed with appropriate colored toner by developer units (55, 56) biased at the appropriate levels.
