Abstract: Disclosed is a negative-chargeable erasable electrophotographic toner including a binder resin, a near infrared absorption dye, a decolorizing agent, a charge controlling agent, and fluororesin particles. The toner is obtained by adding 5 to 20 parts by mass of the fluororesin particles to 100 parts by mass of the binder resin.

Abstract: Desired designated sections are selectively extracted from a color image to be printed, the extracted designated sections are converted into a solid black image having a high thermal energy absorbency, and the solid black image is printed on the foaming layer surface of a supplied thermal expansion sheet. Next, thermal energy is applied by a halogen lamp in a thermal expansion processing unit, causing the solid black image section to expand and rise. Furthermore, in an ink jet printer unit, a prescribed color that is a background color is printed on the entire foaming layer surface of the thermal expansion sheet including the raised sections. Furthermore, the color image to be printed is printed thereon by an ink jet recording method to obtain color image three-dimensional printed material.

Abstract: Disclosed is a method and apparatus for manufacturing a label including providing a release sheet having an adhesive layer on a releasable surface thereof, forming the film-like label portion by electrophotography which includes developing a latent image using the label forming composition to form a solid image of a label shape on a photoconductor, transferring the developed image on the adhesive layer of the release sheet, and fixing the transferred image by applying heat and pressure thereto, and irradiating the film-like label portion and an exposed portion of the adhesive layer other than the film-like label portion with rays to cure the exposed portion.
