Abstract

An electrophotographic image forming apparatus for printing a photographic image and a photographic image printing method by using the same are provided. The electrophotographic image forming apparatus for printing a photographic image includes a photosensitive medium having a surface on which a color-image electrostatic latent image and a transparent-image electrostatic latent image are formed by exposure. At least one color developing unit contains a color glossy toner charged with a polarity and develops a color image on the surface of the photosensitive medium by applying the color glossy toner on the color-image electrostatic latent image. A transparent developing unit contains a transparent glossy toner charged with a polarity different from the polarity of the color glossy toner and develops a transparent image on the surface of the photosensitive medium by applying the transparent glossy toner on an external region of the transparent-image electrostatic latent image. The color image and the transparent image are sequentially transferred without overlapping onto an intermediate transfer medium.

Description

technical field [0001] The present invention relates to an electrophotographic image forming apparatus. More specifically, the present invention relates to an electrophotographic image forming apparatus for printing photographic images. Background technique [0002] Generally, an electrophotographic imaging device is a device for printing a monochrome image or a color image. An electrostatic latent image is formed by irradiating a light beam on the surface of a photosensitive medium charged with a predetermined voltage. The latent image is developed, and the developed image is transferred and fixed to the print medium. [0003] Photographic images developed on photographic paper differ from typical printed images in that photographic images are generally glossy. In order to produce glossy effects with electrophotographic imaging devices, a so-called glossy toner must be used as a developer. However, since the glossy toner is distributed to the image area where the image i...
