Abstract
PURPOSE: To improve the two opposite characteristics thereby to realize an image, which has its resolution improved and its fog reduced, by specifying the shape, diameter and mixture ratio of larger and smaller particles of different types.
CONSTITUTION: A material, which contains tri-silver tetraoxide as magnetic powders, an epoxy resin as a coating resin and carbon black as an electric resistance adjusting agent, is classified. The mixture ratio of the larger toner particles, which have round shape and a diameter ranging from 10 to 100 μ, preferably, 10 to 50 μ, to the smaller toner particles, which have irregular shape and a diameter ranging from 1 to 10 μ, preferably, 5 to 10 μ, is determined to have the 10 to 40 wt.% of the larger toner particles and 60 to 90 wt.% of the samller toner particles. Thus, the resolution can be enhanced, and the carrying property and fluidity of the toners as a whole can be improved so that an image having less fog can be formed.
