Abstract

The present invention provides an electrophotographic image forming apparatus and its method. An electrophotographic image forming apparatus includes a color image forming portion to transfer a color toner to a printing medium to form a color toner image, a fusing unit to fuse the color toner image on the printing medium, a transparent image forming portion to transfer a transparent toner to the printing medium and being detachable, and a guide member to move into a first location in which the printing medium passing the color image forming portion is guided to the fusing unit and a second location in which the printing medium is guided to the transparent image forming portion.

Description

technical field [0001] The present invention relates to an image forming apparatus and a printing method thereof, and more particularly, to an electrophotographic image forming apparatus having a transparent toner and a printing method thereof. Background technique [0002] An electrophotographic image forming device forms an electrostatic latent image by scanning light onto a photoreceptor charged to a uniform potential, develops the electrostatic latent image with a predetermined color toner, and then transfers and fixes the developed image on a printing medium , to print the desired image. Generally, toners of four colors, such as yellow (Y), magenta (M), cyan (C), and black (B), are used in an electrophotographic color image forming device, and four developing units are used to utilize These four color toners develop the electrostatic latent image formed on the photoreceptor. [0003] Toners are manufactured based on plastic resins and thus have a certain glossiness. ...
