Title:
【発明の名称】静電潜像の反転現像方法
Document Type and Number:
Japanese Patent JP2660107
Kind Code:
B2
Abstract:
Process for reversal development of a latent electrostatic image in a layer on a conductive support by developing with an electrostatic developer having electrostatically charged toner particles by (a) generating imagewise areas in the layer having different rates of charge decay and/or charge acceptance, (b) charging the layer, (c) allowing formation of an electrostatic image corresponding to the imagewise generated areas by differential charge decay and/or charge acceptance, (d) creating an electrical field to attract toner particles preferentially to the areas of lesser charge, and (e) developing the areas of lesser charge with electrostatically charged toner particles having the same polarity as that of the charged layer. The developed image can be transferred to a receptor surface, e.g., paper. The process is useful with many type photosensitive masters in preparing reversal images with the use of only one master, toner and film original.
