摘要

High-resolution liquid development process was examined theoretically and experimentally. Recently, we have realized extremely high-resolution (2540 dpi) images on a liquid toner developing system. The mechanisms of reproducing such extremely high resolution are investigated from the viewpoint of the developing process. An electric potential distribution in a single-dot latent image on a photoreceptor is calculated from the exposure energy of high-resolution Laser Scanning Unit (LSU) and surface properties of a photoreceptor. The development characteristics of single-dot images are investigated using numerical simulations of two-dimensional continuity equations based on the electrostatic forces in the development, taking account of the motion of both toner particles and counter ions. The simulation shows that, at an early stage of the development, the toner particles are developed around the edge of the latent image on the photoreceptor, and then the particles are accumulated to form a single dot with horizontal migration toward the center of the latent image. Such developing behavior is characteristic of liquid toner, and the result suggests the mechanism of the high reproducibility of liquid development.
