Abstract

PURPOSE: To make durability sufficiently large, further stabilize friction charging characteristics hence prolong service life by covering nuclide particles with the resin containing the specific surfactant.
CONSTITUTION: A suitable resin and a surfactant, such as the one shown by the formula, which has affinity thereto and has the functional groups -CCOR, -OR, -NCO, -NR2, -N+R3, -CONR2, -SR, -SO3R (R is H, alkyl, aryl, aralkyl, allylene of C1-10 or heterocyclic groups or their derivative salts) and C-F bonds of 40 or under, are dissolved in a solvent. The contents of the surfactant to the resin are preferably 0.1 to 60wt%. By using this solution, the covering layer of thicknesses 0.1 to 30μ, preferably 0.2 to 20μ, is formed on the nuclide particles by a fluidized bed method.
