摘要:
A three-dimensional image recording material for recording images in three dimensions and a three-dimensional image processing method using the said recording material. In forming the recording material, thermoexpansive microspheres each formed by encapsulating a low boiling, vaporizable substance into a microcapsule of a thermoplastic resin are applied onto sheet together with a binder. In forming a three-dimensional image, a desired image is formed on the thermoexpansive coating layer according to an electrophotographic method and then irradiated with light, whereby the toner image area is heated selectively and so that thermoexpansive coating layer expands to raise the image. Then, a laminate film having a heat transferable coloring material layer is put thereon followed by the application of heat and pressure to color the raised image area in a desired color. By providing a film layer on the thermoexpansive coating layer as the surface layer of the image recording material it is possible to not only improve the adhesion of the coloring material layer of the laminate film but also prevent its adhesion to the other portion than the image area.

Disclosed is an oil applying roller provided in contact with the surface of a fixing roller of an electrophotographic copying apparatus. The oil applying roller comprises a core member, an oil retaining layer and a surface layer. The surface layer has less oil retaining ability than that of the oil retaining layer. Thus the oil applying roller can supply a small amount of oil to the fixing roller stably.

A heat roller fixing device for use in an electrophotographic copying apparatus and the like, which includes a heating roller constituted by a fluorine resin layer laminated on an electrically conductive core member through a primer layer the heated roller being driven for rotation, and a pressure roller constituted by an electrically insulative layer on another electrically conductive core member and held in contact with the heating roller for simultaneous rotation with the heating roller so as to fix a charged toner image formed on copy paper onto the copy paper by causing the copy paper carrying the toner image thereon to pass between the heating roller and pressure roller. The primer layer is composed of a primer having incorporated therein an electrically conductive material, and the primer of the primer layer is partly exposed at the surface of the fluorine resin layer. Triboelectric charges produced on the surface of the fluorine resin layer are released by grounding through the primer layer and the electrically conductive core member.
