Abstract: A toner having a medium-resistance external additive, and an image forming apparatus which uses the toner. The medium-resistance external additive coating ratio of particles, of which mother particles have equivalent diameters smaller or larger than a diameter of a mother particle diameter, which is equal to the mean particle diameter of the toner, is set to be higher than a virtual reference curve in synchronous distribution of the particle diameters of synchronous medium-resistance external additive particles, relative to the diameters of mother particles. Further, the medium-resistance external additive coating ratios of particles in a range in which mother particles have diameters smaller than d1, and in a range in which mother particles have diameters larger than d2, are set to be higher than a virtual reference curve in synchronous distribution of the particle diameters of synchronous medium-resistance external additive particles relative to the diameters of mother particles.

Abstract: An image forming apparatus having a tandem system configuration, includes: a multiple number of photoreceptors which each form an electrostatic latent image; and a multiple number of developing devices each holding a different color toner from the others for development of the corresponding static latent image, and is constructed so that the plural toners at least include a black toner, and the abrading force of the black toner or its carrier therein acting on the photoreceptor surface is adjusted so as to be smaller than that of the other developing toners or their carrier therein. Since, in a tandem type color image forming apparatus, the developing devices, photoreceptors and toners for all colors will reach the end of their life at the same time, the image forming apparatus can be operated at low cost.
