发明名称 Electrophotographic method
摘要 A method of making a reproduction copy of an image or a document by electrophotography wherein high print density portions of an original image are developed and transferred onto a recording medium before low print density portions of the original image are developed and transferred onto the recording medium. The original image is multiply scanned under successive, controlled conditions to produce a series of latent images, each of which represents a print density component of the original image. Each latent image is developed and transferred onto the recording medium to produce a composite print density and gradation which closely approaches the print density and gradation of the original document or a predetermined density and gradation.
