A regenerating apparatus of a recording medium by removing a printing material therefrom comprises a holder which is arranged in the liquid and has a plurality of holding members for holding the media; a feeder for feeding the medium to the respective holding members successively; a discharger which includes a discharging passage extending from each of the holding member and out of the liquid for discharging the recording medium having been held by the holding member for a specific time; and a remover which is disposed in the liquid and near the passage so as to contact and remove the printing material from the recording medium transported along the passage.

Regenerating apparatus of recording medium

A regenerating apparatus for removing a printing material from a recording medium so as to reuse the recording medium includes a container, a container for accommodating a liquid for swelling the printing material; a guide member for guiding the recording medium, part of which is arranged in the liquid; a rotatable transporting roller for transporting the recording medium along the guide member, so that the printing material on the recording medium is immersed in the liquid; a rotatable transferring roller disposed near the guide member so as to be in contact at a circumferential surface thereof with the recording medium and receive the printing material swollen by the liquid from the recording medium. The surface of the transferring roller is formed with at least one of the materials selected from polyolefin resin, polyester resin, nitrogen containing resin, sulfur containing resin, fluororesin, silicon resin, polyacetal resin, epoxy resin, polyether ether ketone resin, and phenol resin.

Regenerating apparatus for recording medium

A main body of a regenerating apparatus of a recording medium has a conveyor mechanism which conveys a recording medium to be regenerated along a conveyance passage. A cleaning unit is removably mounted on the main body for easy maintenance, cleaning or replacement. Preferably, the cleaning unit has a U-shaped conveyance passage of the recording medium filled up with a cleaning liquid, and an image removing mechanism which applies a physical treatment to the surface of the recording medium. The recording medium is taken in the U-shaped conveyance passage, immersed in the cleaning liquid so that the image on the recording medium is swollen and removed by the image removing mechanism. The image removing mechanism may include a web impregnated with cleaning liquid brought into contact with the recording medium by a roller which may have a built-in heater to cause the printing material on the recording medium to swell and be scraped off by the web.

An apparatus for regenerating a recording medium has a feeder which feeds a recording medium, a transporter which transports the recording medium, an immersion bath for containing a cleaning liquid for swelling prints and immersing the recording medium in the cleaning liquid, a print remover which removes the prints by subjecting the surface of the recording medium to a physical treatment, and a fluidizing structure for fluidizing the cleaning liquid in a direction opposite to a direction in which the recording medium is transported in the immersion bath.

Apparatus for regenerating recording medium

The present invention relates to a cleaning liquid which is used for removing an image forming material containing a resin component from surface of a recording medium on which an image is formed by the image forming material in order to permit the recording medium serviceable again as a recording medium, characterized by comprising water, a gelatinizer or a swelling agent which is compatible with water and gelatinizes the resin component of the image forming material, and an enzyme.

Cleaning liquid for recycling copy medium for electrophotography

The present invention relates to a method for fixing images formed by a printing material containing a resin component on a recording medium, comprising: a first step of providing the printing material to the recording medium to form the images, and a second step of contacting the printing material provided on the recording medium with a fixing solution to fix the printing material on the recording medium, the fixing solution comprising a monoester of bivalent organic acid.
