Abstract

PURPOSE: To increase the resistance of the magnetic toner for PPC composed mainly of magnetic powder and thermoplastic resins by covering the magnetic powder with a Ti-base coupling agent.
CONSTITUTION: The solution of the Ti coupling agent of the formula (RO)mTiXn (R is alkyl; m is 1 to 3; X is fatty acid groups, hydrocarbon groups of phenol groups; n is 1 to 3) and magnetic powder are mixed, then the coupling agent causes reaction with the OH groups on the surfaces of inorganic material and is thereby fixed on the surfaces. The magnetic powder thus prepared is mixed and kneaded with thermoplastic resins under heating, after which the mixture is ground. This yields the toner of good fluidity and high resistance and enables the good images free from for and of high resolution to be obtained even with paper of low resistance.
