Toner for amorphous silicon photoreceptor and developer including the same

摘要

Toner and developer including the toner is operable to prevent blurring from occurring in an image forming system including an amorphous silicon photoreceptor, and to assure high image quality and image free from fog even under high humidity environment. Coloring particles each comprise a main particle including a polyester resin having an acid value of not less than 20 as a binder resin, and a hydrophobic silica whose primary particle has a mean particle size of from 7 to 20 nm, and magnetic powder whose primary particle has a mean particle size of from 100 to 1000 nm, adhered to the surface of main particle.
