ABSTRACT:
An electrophotographic method is disclosed, in which electrostatic latent images are formed on an electrophotographic photoconductor by exposure of the photoconductor to a light beam, and the formed electrostatic latent images are developed to visible toner images by a developer comprising toner particles, with the minimum diameter D of the light spot of the light beam on the photoconductor and the volume mean diameter X.sub.w of the toner particles being in the relationship of (D).mu.m.gtoreq.9.0.times.(X.sub.w).mu.m-34.
