摘要: An improvement of a medium for electrophoresis which comprises a support of a plastic material and an aqueous polyacrylamide gel, wherein a resin layer comprises a resin having an oxygen permeability coefficient lower than that of the plastic material of the support is arranged betwen the support and the polyacrylamide gel. The resin preferably shows an oxygen permeability of not more than 15 cc/m.sup.2 .multidot.atm.multidot.day in the form of a resinous layer of 20 .mu.m thick, and exemplified by a vinylidene chloride-vinyl chloride copolymer, polyvinyl alcohol, polyacrylonitrile, polyvinylidene chloride, a vinyl alcohol-ethylene copolymer, a vinylidene chloride-acrylonitrile copolymer, and an acrylonitrile-methyl acrylate-butadiene copolymer.

摘要: This invention is a method for manufacturing an electrophotographic developer for use in electrophotography or electrostatic recording processes. The developer comprises polymer particles by suspension polymerizing, in an aqueous phase, a polymerization liquid comprising at least one polymerizable vinyltype monomer, a polymerization initiator, and a finely divided dispersion stabilizer either sparingly soluble or insoluble in water and said monomer. Said polymerization liquid is blended prior to suspension polymerization. The improvement includes adding to said liquid, a resinous substance, as a fluidizer which is soluble in the monomer and having a solubility parameter in the range of from 7.8 to 16.1. During the blending, the dispersion stabilizer is uniformly dispersed throughout said polymerization liquid. Next, the blended polymerization liquid containing the fluidizer is suspended in the aqueous phase and then such blend is subjected to said suspension polymerization to effect polymer particles having diameters in the range of 0.1 to 100.mu..
