Abstract
The present invention can provide an electrophotographic apparatus and electrophotographic method which are less affected by dot gain, can realize smooth gray scale expression, are high in gray scale reproducibility, and are hard to generate moire. In an embodiment of the present invention, a continuous tone image is binarized by using the frequency modulation screening, to form a latent image free from the generation of moire and high in relative resolution. The latent image thus formed is developed using a liquid developer, to form a thin toner layer, for forming a toner image less in the generation of mechanical and optical dot gain.
