摘要： This invention relates to image formation toner, 2-component developer, image formation method and method for manufacturing image formation toner, for preventing clogging of the filter. Toner is used in which the ratio of the component measured by GPC to have a molecular weight between 500 to 1000 is 10 parts by weight or less with respect to 100 parts by weight of the entire toner. Since the case of clogging of the HEPA filter is the 500 to 1000 molecular weight component, clogging of the filter is prevented by reducing this component.

摘要： An electrification enhancer is either contained in the photoconductor, is present as a coating on the surface thereof, or is applied prior to use. A compound such as ammonium fluoride, a ferroelectric substance, a high molecular substance (fluorine resin) with an equivalent work function of 4.10 or greater, etc. are effective. The chargeability of the photoconductor is improved. The construction is best suited for the rear photorecording process, but is also effective in other types of contact charging recording systems.

摘要： Toner magnetic powder which uses a resin as a binder and contains a dye is coated by a methyl methacrylate resin, thereby forming a carrier. A developer is formed by such a carrier in which those two components are mixed. An electric conductivity of the impurity extracted water of the carrier due to the pressurization in the pure water is set to 60 .mu.S/cm or less. Namely, the purity is improved so that the electric conductivity of the impurity extracted water of the methyl methacrylate resin due to the pressurization in the pure water is set to 20 .mu.S/cm or less, and the purity is improved so that the electric conductivity of the impurity extracted water of the magnetic powder due to the pressurization in the pure water is set to 60 .mu.S/cm or less, thereby forming a carrier. A carbon addition amount upon manufacturing of the carrier is controlled so that the electric resistance of the carrier is set to a value within a range of 1.times.10.sup.4 to 1.times.10.sup.8 .OMEGA.cm. Further, a carbon addition amount upon manufacturing of the toner is limited so that the electric resisance of the toner is set to 1.times.10.sup.11 .OMEGA.cm or more.
