Abstract

PURPOSE: To form always stabilized sharp fog-free images by adding finely divided magnetic particles surface-treated with a specified silance compound.
CONSTITUTION: Magnetic material fine particles, preferably of 0.1W1 micrometer size is treated with a solution of a silane compound represented by formula SiX3 in which R is an organic functional group having a terminal vinyl group and X is a group converting into an OH group on hydrolyzing, or further with a solution containing a resin and a dye in order to improve surface property and color tone. These surface-treated magnetic fine particles are melted together with a toner binder, when needed, a charge controller, a dcolorant, or the like and kneaded, and then, pulverized. This magnetic toner 6 is fed from toner feeder 4 to rotatable stainless sleeve 3, attached to sleeve 3 with fixed magnets 2, and the attached amount is controlled with doctor blade 5 to develop the electrostaitc latent image on photosensitive durm 1.
