Problems solved by technology

[0017] However, the techniques of Patent Document 1 and Patent Document 6 above have problems such as constant supply of uniform transparent toner throughout the entire surface, and a large load on the fixing unit due to the difference in toner thickness between the image part and the non-image part.
[0018] In addition, in order to use the technology of Patent Document 2, the special fixing device shown in Patent Document 3 is used, and the effect can be achieved, but there are problems such as complicated structure, high cost, and large power consumption.
[0019] Therefore, in the background technology, in order to obtain a high-gloss image like a photograph, a recording medium of a special material is used, or after the usual image is formed and fixed, it is cooled by a special fixing device, which is time-consuming and poor in productivity. Corresponding difficulties

Abstract

The invention relates to an image forming apparatus capable of using a recording medium having a transparent portion. The image forming apparatus includes an image forming unit for forming an image on the recording medium plane, a fixing unit for fixing the image and forming the image on the recording medium plane through the image forming unit, and an applicator for coating non-transparent liquids to at least the fixed image on the face of the recording medium. The invention provides an image forming apparatus with good collection property picture-quality images with a simple structure.

Description

technical field [0001] The present invention relates to an electrophotographic image forming apparatus, and more particularly, to forming an image using a recording medium that can pass through a paper and at least partially has a transparent portion, Background technique [0002] Conventionally, in an electrophotographic image forming apparatus, various methods have been tried in order to obtain a glossy photographic image quality image (see, for example, Patent Documents 1 to 5). [0003] For example, Patent Document 1 proposes a so-called tandem printer in which processing units are arranged side by side. It is provided with, for example, yellow (Y), magenta (M), cyan (C), and black (B) as image forming machines for each color. The processing unit is further provided with a developer with white toner and a developer with clear toner. [0004] In this printer, a color toner image composed of yellow (Y), magenta (M), cyan (C), and black (B) four-color toners is first forme...
