Abstract
Provided is a liquid development apparatus which can restrain carrier liquid in a liquid developer from being evaporated and diffused into the atmosphere, which has a simple and convenient arrangement, and in which a recording medium formed thereon with an electrostatic latent image in accordance with image data is transferred and the electrostatic latent image on the recording medium is developed by a developer in a liquid developer in which toner particles are dispersed. The liquid development apparatus includes a developer supply for feeding the developer containing non-volatile components having a density of 10 to 30 wt. %, a developer holding member having a surface roughness in a range from 8 to 25 .mu.m Rz, for holding the developer fed from the developer supply, and a conductive member facing the developer holding member, interposing the latent image bearing recording medium on which the electrostatic latent image is formed, between itself and the developer holding member, for applying an electric filed between itself and the developer holding member in a direction in which the toner particles are shifted from the developer holding member toward the latent image bearing recording medium.
