Magnetic toner for developing latent electrostatic images and a process for the preparation thereof |
摘要 |
A one-component developer for developing a latent electrostatic image which comprises magnetic particles, thermoplastic resins and electric charge controlling dyestuffs as main components and in which the magnetic particles are substantially coated with the electric charge controlling dyestuffs. The resulting toner forms no fringe or ghost and has good duplicativity of halftone images. The toner is made by coating the magnetic particles with the electric charge controlling dyestuffs before mixing the magnetic particles with the resin.
