Abstract

An insulative magnetic toner disclosed herein comprises a magnetic powder, a negative charge control agent, a binder resin and a compound having phenazine ring amorphous-silicon photoreceptor.
The magnetic toner according to the invention is effective for preventing the occurrence of picture image blurring under high humidity when used in an amorphous-­ silicon photoreceptor.
