PURPOSE:To obtain the titled material having an improved electrostatic charge characteristics of a toner by incorporating a diorganotin borate to at least the surface of the titled material. CONSTITUTION:The carrier type electric charge imparting material is obtd. by dissolving the diorganotin borate in a solvent, followed by dispersing it, and by dispersing the carrier of iron powders to the obtd. dispersion, followed by agitating it in a ball mill, and subsequently, drying the mixture until the solvent is completely removed, and by disassembling the obtd. weak cohesive material. Thus, the titled material which does not decrease the electrostatic charge and does not disorder a latent image by repeating a development, is obtd. The titled material facilitates the electrostatic charge, without injuring a color tone of the color toner. |
