Abstract:
A method of forming an image comprising the following sequential steps:forming an electrostatic latent image on an organic photoconductive drum;applying a developer containing toner particles to a sleeve in which a permanent magnet member is disposed;developing the electrostatic latent image by relative rotation of the sleeve to the permanent magnet member such that a magnetic brush is formed on the sleeve, the magnetic brush brushing the surface of the photoconductive drum, whereby a toner image is formed;transferring the toner image to a transfer means;fixing the transferred image; andcleaning the remaining toner particles from the image carrier with a fur brush;wherein said toner particles comprise at least one binder resin and a colorant; from 0.1 to 3 parts by weight, per 100 parts by weight of said toner particles, of finely powdered cleaning assistant is disposed on the surface of said toner particles; said toner particles have an average size of 2 to 9 .mu.m; said toner particles are produced by polymerization; and said cleaning assistant is at least one oxide of a rare earth element having an average particle size of 0.01 to 0.5 .mu.m.
