Problems solved by technology

However, in order to impart heat for immediately erasing images to the reusable paper presented by the user, the above-mentioned erasing mechanism usually needs to maintain residual heat.
In such an application, a lot of energy is wasted
In addition, in the thermal head, due to friction on the paper surface, ink or toner, etc. adhere to the head, resulting in a significant decrease in erasing performance.

Embodiment Construction

[0029] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings.

[0030] First, a first configuration example of the image forming apparatus according to this embodiment will be described.

[0031] figure 1 and figure 2 A first configuration example of the image forming apparatus 1A is shown. figure 1 and figure 2 The illustrated image forming apparatus 1A includes a paper cassette 10 , a collection section 11 , a printing section 12A, a paper discharge tray 14 , a paper feed tray 16 , a recycling processing section 18 , and the like.

[0032] The above-mentioned paper cassette 10 is a cassette for accommodating paper. The paper cassette 10 holds the printing paper P on which the image is printed by the above-described printer 12A. The above-mentioned collecting unit 11 collects paper sheets that are not to be reused (reused). The above-described printer 12A forms an image on the sheet P. exist figure 1 and figure 2 In t...

Abstract

The invention provides an image forming apparatus and a paper treatment method, image eliminating device. Wherein, the image forming apparatus picks up each one of sheets stacked in a tray, allows a detecting sensor to detect whether a mark indicating a reusable sheet is assigned to the picked-up sheet, and cumulates the sheet in which the mark is not detected by the detecting sensor in a cumulative unit. The image forming apparatus erases a color of an image forming material by heating the sheet of which the mark is detected by the detecting sensor and receives the sheet of which the image forming material is erased in a sheet cassette. The image forming apparatus forms an image with the image forming material erasable by applying heat to the sheet received in the sheet cassette.

Description

technical field [0001] The present invention relates to an image forming apparatus for forming an image using an erasable image forming material, an image erasing apparatus for erasing an image formed using an erasable image forming material, and the like. Background technique [0002] Currently, as printing methods in printers, there are various methods such as an electrophotographic method, an ink jet method, a thermal recording method, and a thermal transfer method. In recent years, a method of reusing (reusing) paper used in printers has been proposed in order to reduce the environmental burden or reduce the amount of carbon dioxide emitted. For example, Japanese Patent Laid-Open No. Hei 06-155906 proposes a method of rewriting an image multiple times using a sheet that can be colored or decolorized by heat. Also, in Japanese Patent Laid-Open No. 11-268409, there is proposed a method of reusing the paper by eliminating the image printed on the paper with the decolorizab...
