Problems solved by technology

[0003] However, when the color-erasable recording agent and the non-erasable recording agent are the same color, it is difficult to distinguish which recording agent is used to print the sheet.
In this case, if printing is performed with a non-erasable recording agent on the back of a sheet printed with an erasable recording agent, the recycling rate of the sheet may decrease

Embodiment Construction

[0014] Hereinafter, an image forming apparatus according to an embodiment will be described with reference to the drawings.

[0015] figure 1 It is an external view showing an example of the overall configuration of the image forming apparatus 1 according to the embodiment.

[0016] The image forming apparatus 1 is a multifunction peripheral (MFP; Multi Function Peripheral: Multi Function Peripheral) capable of forming a toner image on a sheet S. As shown in FIG. The sheet S is, for example, a document, paper on which characters, images, etc. are written, or the like. The sheet S may be any item as long as it can be read by the image forming apparatus 1 . The image forming apparatus 1 reads the image displayed on the sheet S to generate digital data, and generates an image file.

[0017] The image forming apparatus 1 includes an image reading unit 10 , a control panel 20 , a printing unit 30 , a sheet storage unit 80 , a sensor 90 , and a control unit 100 . In addition, th...

Abstract

The invention provides an image forming apparatus capable of improving the reuse rate of a sheet. The image forming apparatus comprises a sensor, a printer and a controller. The sensor is used to detect on a sheet an image representing printing of the sheet with a decolorable recording agent comprising a coloring material to be decolored from the sheet. The printer carries out a printing operation of the medium of an image formed with the decolorable recording agent and a printing operation of the medium of an image formed with a non-decolorable recording agent comprising a coloring material that is not decolored. In a case in which the image is detected by the sensor, the controller controls the printer to execute the printing operation with the decolorable recording agent on the sheet.

Description

technical field [0001] Embodiments of the present invention relate to image forming apparatuses. Background technique [0002] Conventionally, there is known an image forming apparatus capable of decolorizing a printed sheet with a recording agent containing a decolorizable toner (hereinafter referred to as “decolorizable recording agent”). For example, the image forming device is a multifunction machine such as an MFP (Multi Function Peripheral: Multi Function Peripheral). A sheet decolorized by an image forming apparatus having such a decolorizing function can be reused. In addition, since the decolorizable recording agent is blue, it is easy to distinguish it from a sheet printed with a recording agent containing a non-decolorizable toner (hereinafter referred to as "non-decolorizable recording agent"). [0003] However, when the color-erasable recording agent and the non-erasable recording agent are the same color, it is difficult to distinguish which recording agent p...
