摘要:
A gloss-imparting device for imparting a gloss on a color image, the gloss-imparting device has a transparent toner image-carrying body, a transparent toner image-forming unit, a heating/pressurizing unit, and a cooling/releasing unit. The transparent toner image-carrying body carries a transparent toner image formed of a transparent toner thereon. The transparent toner image-forming unit forms the transparent toner image on the transparent toner image-carrying body. The heating/pressurizing unit heats and pressurizes the transparent toner image and the base material to bring them into contact. The cooling/releasing unit cools the transparent toner image and releases the base material from the transparent toner image-carrying body. The transparent toner image is transferred and fixed onto the base material by the heating/pressurizing unit.

摘要:
A color image forming device and method prevent occurrence of pile height moires specific to electrophotographic images in low-frequency areas and conventional moires in a digital screen set of four colors. In the color image forming device, by at least one of a halftone generating part and scanning signal forming unit in an image processing unit, differences among screen angles of three dot patterns corresponding to cyan, magenta and black toner images are in the range about 25 to 40 degrees, preferably 30 degrees; the screen angle of a first dot pattern corresponding to a yellow toner image is made equal to that of a second dot pattern corresponding to the toner image of one of cyan, magenta and black; and the screen of the first dot pattern is brought about 150 to 210 degrees, preferably about 180 degrees out of phase with the screen of the second dot pattern.

摘要:
A system includes an image formation apparatus, an image retrieval server, and image storage servers, and a network for connecting them. The image formation apparatus forms an image based on image data, records the image data in a predetermined storing location on the image storage servers, converts the image data under a predetermined rule to generate an image identification information as a key in order to read the image data from the storing location, and outputs the image identification information. Upon reception of an image data retrieval request together with an image identification information, the image retrieval server determines that the image data whose result of conversion under the predetermined rule is equal to the image identification information, among at least one image data stored in a predetermined storing location on the image storage servers, is the image data to be retrieved, and outputs its information.
