摘要： PROBLEM TO BE SOLVED: To provide an image receiving sheet with which a toner image can be formed by separably and removably holding the image without fixing the image like heretofore and consequently the held toners can be separated and removes and reutilized and also the toner image can be well formed and the formed toner image can be well held. SOLUTION: The image receiving sheet S for forming the toner image by removably sticking the toners T has a rugged surface with a multiplicity of continuous groove-like recessed parts R which are capable of accepting the toners T formed thereon and are capable of forming the toner image by removably sticking the toners T to the recessed parts R. The image receiving sheet is so formed that the toners sticking to the recessed parts R are protected by the projecting parts P of the rugged surface of the image receiving sheet. The depth (the height of the projecting parts P) of the continuous groove-like recessed parts R of the image receiving sheet S is 20 to 150 μm and the conditions E.A>=2 (GPa.μm) hold when the Young's modulus when the material forming the recessed parts R and the projecting parts P elongates 1% is defined as E (GPa) and the width of the projecting parts P as A (μm).

摘要： PROBLEM TO BE SOLVED: To form a high-quality image by using a reversible static image display medium which can repeatedly display images and by subjecting the medium to the initialization treatment such as erasing images before displaying an image and (or) by allowing the developing particles to easily move for displaying an image. SOLUTION: An image is displayed by using a reversible image display medium D1 which houses a developer DL containing white developing particles WP and black magnetic developing particles BP having triboelectrification property and different electrification polarities and different optical reflection densities from each other in cells 116 between two substrates 111, 112 and which can display an image by applying an electrostatic field according to the image to be formed so as to drive the developing particles. Prior to the image display process and (or) in the image display process, an oscillating magnetic field is applied on the developer DL in the image display medium D1 by using devices IN4 and (or) IN5 which impart magnetic stirring force to generate stirring force.

摘要： PROBLEM TO BE SOLVED: To stably display an image by using a reversible static image display medium which can repeatedly display images. SOLUTION: An image is displayed by using a reversible image display medium D2 which houses a developer DL containing white developing particles WP and black magnetic developing particles BP having triboelectrification property and having different electrification polarities and different optical reflection densities from each other in cells 116 between two substrates 111, 112 and which can display an image by applying an electrostatic field according to the image to be formed as well as applying oscillating force (e.g. an oscillating magnetic field) to drive the developing particles. The oscillating force (e.g. an oscillating magnetic field) is substantially stopped while the electrostatic field is applied. After application of the electrostatic field is ended, the image observation surface is electrified to the image holding potential.

摘要： PROBLEM TO BE SOLVED: To obtain an electrophotographic liq. developer attaining a developing speed required in practical use, less liable to cause the settling of the toner and facilitating redispersion even when the toner settles by using an electric insulating carrier soln. in which a toner having internal voids and a specified vol. average particle diameter has been dispersed. SOLUTION: In this electrophotographic liq. developer contg. a toner dispersed in an electric insulating carrier soln., the toner has one or more internal voids and 0.5-5 μm vol. average particle diameter (d50 ). By this vol. average particle diameter (d50 ), developing speed required in practical use and high resolution are attained. Since the toner has internal voids, the specific gravity of the toner is low and the difference in specific gravity between the toner and the carrier soln. is reduced to reduce the rate of settling of toner particles. Even when the toner settles, the redispersion is facilitated. A toner sediment is not made dense and the blocking of a settled toner is hardly caused.

摘要： PROBLEM TO BE SOLVED: To obtain a cleaning device capable of restraining the wear and the damage of the surface of an electrostatic latent image carrier and the failure of an image caused by them and prolonging the life thereof by removing residual toner on the electrostatic latent image carrier by toner attracting action to a cleaning member by bias voltage. SOLUTION: This cleaning device 7 removes the residual toner D2 which is not primarily transferred and left on a photoreceptor 1. A cleaning roller 71 is arranged by leaving a fixed space between the photoreceptor 1 and the roller 71, and driven to be rotated in a direction a4. A bias impressing device 72 impresses the bias voltage from a power source PW6 between the photoreceptor 1 and the roller 71 in order to attract the residual toner D2 adhered on the photoreceptor 1 to the roller 71. A scraper 73 is arranged in contact with the roller 71 in such a posture that the removed toner D3 is easily guided downward in order to remove the toner D3 attracted on the roller 71 by the impressing of the bias voltage.

摘要： PROBLEM TO BE SOLVED: To provide a method and apparatus for forming an image onto a non-fixing system image receiving sheet so that smear resistance is satisfactory, and to provide a sheet reproducing method and device by which toner is smoothly removed from the sheet and the sheet is reproduced so as to be reusable. SOLUTION: The method and apparatus are for forming an image on the non-fixing system image receiving sheet 1 which has, on its surface, groove-like recesses s1 and projections s2 formed along the recesses, allows the formation of a toner image by removably attaching toner T to the recesses, and protects the toner image with the projections. In the method and apparatus, after the toner image is formed by attaching the toner T to the recesses s1 of the sheet 1, heat is applied to the toner T forming the toner image, then the toner particles are slightly melted to such a degree that the toner can be removed from the sheet. The sheet on which the toner image is formed can be recycled by removing the toner image with a toner reproducing device 6. COPYRIGHT: (C)2005,JPO&NCIPI
