PURPOSE:To give a toner proper negative triboelectrifiability by coating the surface of a carrier or the like with a metal complex of optionally substd. picolinic acid deriv. to form a material for triboelectrifying the electrostatic charge image developing toner. CONSTITUTION:The complex of picolinic acid deriv. optionally substd. by at least one of Cl, nitro, methyl, ethyl, or the like represented by formula I, II, or the like of a metal, such as Fe, Cr, Mg, Cd, Co, Pt, or Ag, is synthesized. The surface of the carrier, sleeve, or doctor blade is coated with said metal complex to form the material for electrifying the toner. To embody this process for the carrier, the surfaces of the carrier cores are dipped in a vessel contg. a soln. dissolving or dispersing said complex, or sprayed with said soln., or treated by the fluidized bed process to attach it to the surfaces of the cores. |
