PURPOSE:To obtain a clear which does not generate ground fogging using a toner contg. a metal oxide particle having a specific saturation magnetization for the titled agent. CONSTITUTION:The titled agent is composed of the toner contg. a magnetic carrier, a binder resin and a coloring agent. The toner contains 1-30wt.% of a magnetic metal oxide particle having <=1mum mean particle size and the saturation magnetization of 10-40emmu/g. The electrification of each toner particles makes uniform, and is stabilized for a long period by incorporating the magnetic metal oxide particle in the toner, and the scattering and the ground fogging of the titled agent are prevented. |
