ABSTRACT:
An apparatus for developing an image with spherical toner particles has a latent image carrier on which a latent image is formed by a potential contrast, a toner transporter having a surface for transporting the spherical toner particles to the latent image carrier and an elastic blade having a surface for passing the spherical toner particles transported by the toner transporter through a gap between the surfaces of the toner transporter and elastic blade for forming a thin toner layer which is charged. The toner transporter is elastically deformed for the surface thereof to be brought into pressure contact with the latent image carrier and develop an electrostatic latent image on the latent image carrier with the thin toner layer which is charged. Surface roughnesses of the elastic blade and of the toner transporter are different from each other. The toner particles are rotated between the elastic blade and the toner transporter and charged electrostatically. At least some of the toner particles may also satisfy the equation b/a=1 to 1.5 where "a" is the longest length of the minor axis and "b" is the longest length of the major axis of at least one cross section of the toner particles.
