发明名称 Electrophotographic recording method.
摘要 <p>In an electrophotographic recording method in which electric charge is uniformly applied to the surface of a photoconductive drum (1), the drum surface is then exposed to a first information light beam (3A) to form a first negative latent image, the first negative latent image is developed with a first two-component developer (4B), the drum surface is further exposed to a second information light beam (5A) to form a second negative latent image, and the second negative latent image is developed with a second two-component developer (6B) to produce a two-color toner image, the toner content (a2) in the second two-component developer is made larger than that (a,) in the first two-component developer.</p>
