PURPOSE:To use color toners of small grain sizes and to improve transferability and cleanability by using the color toners formed by fixing fine resin powder to the particle surfaces of particle powder for the toners. CONSTITUTION:The toner images by the respective color toners are superposed on an image forming body and thereafter, the toner images are simultaneously transferred and the toners remaining on the image forming body are cleaned. The color toners formed by fixing the fine resin powder 51 to the particle surfaces of the particle powder 52 for the spherical toners having 2 to 8mu average grain size are used as the color toners. Namely, the hardly desorbable ruggedness by the fine resin powder 51 are formed on the surfaces of the color toner particles. The physical adhesive strength and electrostatic adhesive strength of the color toners to the image forming body are, therefore, weakened. The transferability of the color toner images superposed in the simultaneous transfer stage is improved in this way and the cleanability of the color toners remaining on the image forming body is improved in the cleaning stage. |
