DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming substance removing apparatus, and more particularly, to an image forming substance for reliably removing an image forming substance from an image carrier and reproducing the image carrier in a reusable state. It relates to a removing device.

[0002]

2. Description of the Related Art With the recent introduction of OA (Office Automation), information is recorded on recording paper by a printer, a copying machine, or the like. In offices, paper such as printer paper or copy paper on which this information is recorded is used. Is generated in large quantities, but at present, most of the paper is wasted.

[0003] Disposal of paper on which such information is recorded requires a great deal of cost, and also degrades the local environment due to the disposal, and consequently reduces the global environment due to deforestation for producing paper. Leads to deterioration.

Heretofore, in order to solve this problem and to recycle paper, measures have been taken to remove used ink on the paper once used, soak and re-use it, and use it as recycled waste paper.

[0005] In the process of recycling used paper, a large-scale used paper recycling facility is required.
A number of processes had to be taken, such as sorting, collection, and transportation, to obtain recycled paper.

In recent years, paper has been developed which can remove a character image on paper used once by cleaning and reuse it for copying or printing. For example, JP-A-1-101576 discloses that an image forming support (paper) on which an image is formed with an image forming substance (toner) is subjected to ultrasonic treatment in an organic solvent that dissolves the image forming substance. An imaging substance removal method for removing an imaging substance from an imaging support is disclosed.

Further, a solvent is applied to the printed portion of the waste paper by immersion, spraying, coating or the like to dissolve the toner, and the dissolved toner is washed, air suctioned, adsorbed, and the like.
There has been proposed a method of removing an image forming substance which is removed by a method such as mechanical peeling or electrostatic adsorption (Japanese Patent Laid-Open No. 4-30 / 1990).
0395).

Further, the applicant of the present invention has previously described that an image carrier having been recorded is provided with water as a destabilizing solution, an aqueous solution containing a surfactant, an aqueous solution containing a water-soluble polymer, and a surfactant and a water-soluble polymer. And a method for removing at least one type of water or aqueous solution from an aqueous solution containing: and a peeling member, and bonding the image forming substance to the peeling member by heat or pressure to peel off from the image holding member. (See Japanese Patent Application Laid-Open No. 7-84396).

According to these, only the image forming substance can be removed from the image holding member without relatively damaging the paper quality of the image holding member.

In addition, the applicant of the present invention reduces the fixing power of the image forming substance to the image carrier as a pre-treatment of the means for removing and peeling the image forming substance, thereby facilitating the peeling of the image forming substance from the image carrier. In the image forming substance removing apparatus for transferring and removing the image forming substance to the peeling member after applying the image removing accelerating liquid after applying the liquid, a part of the image forming substance is removed before applying the liquid. By subjecting the microscopic gap in the image formed of the image forming substance to a process of damage or destruction of the image formed of the image forming substance, and efficiently holding the image removal promoting liquid with the image forming substance. There has been proposed an image forming substance removing apparatus having means for invading an interface with a body (see Japanese Patent Application Laid-Open Nos. 7-20754 and 7-175255).

Further, in an apparatus for removing an image forming substance on an image carrier using an image removal accelerating liquid, at least one type of silicone-based material is used in order to improve reproduction failure caused by silicone at the time of copy fixing. An image removal accelerating liquid characterized by containing a surfactant has been proposed (see JP-A-7-234535).

According to this, the affinity between the silicone, and thus the toner to which the silicone adheres, and the image removal accelerating liquid are improved, and the repelling between the toner and the image removal accelerating liquid is less likely to occur. The adhesive force between the holder and the image forming substance can be efficiently reduced, and the ability to remove the image forming substance can be improved.

[0013]

However, in the above-mentioned publications, there is still room for improvement in removing the image-forming substance from the image carrier efficiently and reliably. .

That is, in the method for removing an image described in JP-A-1-101576, since an organic solvent is used, there is a new problem that pollution is caused by the organic solvent, and the organic solvent is ignited. Due to its toxicity and toxicity, care must be taken in its handling, and there is still a problem in using it in ordinary offices and homes.

In the method of removing an image forming substance described in Japanese Patent Application Laid-Open No. 4-300395, a method in which a toner is dissolved and the dissolved toner is washed, suctioned by air, contacted with an adsorbent, mechanically peeled, or electrostatically adsorbed. Therefore, there has been a problem that the image forming substance removing apparatus becomes large and expensive.

Further, Japanese Patent Application Laid-Open No.
