Problems solved by technology

[0005] However, when the recording medium is repeatedly reused or images are formed at high density on a wide area of ​​the recording medium, it becomes unsuitable for reuse.
That is, the image quality of the image formed may be degraded
In addition, the thickness of the recording medium becomes thicker than the thickness of the developing material that repeatedly performs image formation, so the life of components such as the photoreceptor drum and the transfer roller is shortened.
[0006] The existing recording medium identification device detects whether the developing material is decolorized after the decolorizing operation, and cannot determine whether the decolorized recording medium after forming an image with the decolorizable developing material is suitable for reuse

Abstract

The invention provides an erasing apparatus, an image forming apparatus and a recording medium identifying method. The recording medium identifying device includes a sensor set downstream in a recording medium conveying direction of a heating device and configured to detect reflected light of a recording medium, and a control section configured to calculate a printing ratio of the recording medium and determine, if the printing ratio of the recording medium is equal to or larger than a threshold, that the recording medium is un-reusable. The erasing apparatus includes the recording medium identifying device, a heating device configured to heat the recording medium to temperature equal to or higher than erasing temperature, a switching mechanism configured to switch a recording medium conveying path, and a disposal box in which unusable recording media are stored. If the control section determines that the recording medium is un-reusable, the control section controls the switching mechanism and stores the recording medium in the disposal box.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims the benefit of priority from US Provisional Patent Application Serial No. 61 / 318,235, filed March 26, 2010, the entire contents of which are hereby incorporated by reference. technical field [0003] Embodiments of the present invention relate to a color erasing device, an image forming device, and a recording medium identification method. Background technique [0004] In order to save resources, image formation may be performed using a decolorizable developing material. As a decolorizable developing material, there are toners, inks, and the like whose color disappears due to heat. The recording medium on which an image is formed by the decolorizable developing material is reused after being heated and decolorized by the decolorizing device. [0005] However, when the recording medium is repeatedly reused or images are formed at high density on a wide area of ​​the recording ...
