摘要:
A method of repetitively using a sheet or similar toner image carrier produced from an image forming apparatus, and a toner applicable thereto. A toner forming an image on the toner image carrier is removed to erase the image. The toner image carrier is implemented as a synthetic sheet. Use is made of a toner whose adhering force to the sheet is weaker than the adhering force of a conventional toner.
摘要:
A developing device develops a latent image formed on a latent image carrier by supplying a developer to the latent image carrier. The developer comprises a carrier liquid and a toner dispersed in the carrier liquid. A gelling agent adding device adds a gelling agent to the developer remaining in the developing device so as to gel the developer.
摘要:
A fixing device for an image forming apparatus and having a heating member facing a sheet transport path. The heating member has a number of heating portions which are separate in a direction perpendicular to an intended direction of sheet transport. The heating portions are selectively driven in matching relation to a toner image carried on a sheet.
摘要:
An image-receiving sheet for use with an electrophotographic method, including a transparent support and an overcoat layer formed thereon is disclosed, in which the overcoat layer (i) includes a thermoplastic resin which has a fluidification initiation temperature lower than that of a toner for image formation to be employed or that of a resin for use in said toner, and (ii) is white and opaque from being in a porous state. Furthermore, an electrophotographic method using the above image-receiving sheet is also disclosed.
摘要:
A control device for image forming equipment capable of reducing ozone ascribable to an image forming process and detecting failures of the equipment caused by the ozone. Mists are produced from a liquid developer which is a toner-dispersed carrier liquid containing silicone oil during developing, image transferring and fixing steps. The mists and the ozone are discharged to the outside of the equipment by a fan. A filter liquifies the mists and ozone by mixing them together. Errors are detected on the basis of ozone concentration which is sensed by an ozone concentration sensor.
摘要:
A liquid developer for use in electrophotography which is prepared by dispersing a pigment or dye and a resin in a carrier liquid comprising a nonaqueous solvent having a high insulating property and a low dielectric constant, wherein said resin comprises those obtained by grafting, upon a copolymer comprising a monomer having the general formula ##STR1## [wherein R is --H or --CH.sub.3 and X is a phenyl group, a methylphenyl group, --COOC.sub.n H.sub.2n+1 (1.ltoreq.n.ltoreq.20) or --COOC.sub.2 H.sub.4 N(C.sub.m H.sub.2m+1).sub.2 (1.ltoreq.m.ltoreq.5)], a monomer having a glycidyl group and a unsaturated carboxylic acid or its anhydride, in particular the unsaturated carboxylic acid or its anhydride when the copolymer has the glycidyl group as the constitution unit, and the monomer having a glycidyl group when the copolymer has the unsaturated carboxylic acid or its anhydride as the constitution unit.
