Title:
ELECTROSTATIC LATENT IMAGE DEVELOPING DEVICE
Document Type and Number:
Japanese Patent JP3013331
Kind Code:
B2
Abstract:
PURPOSE: To provide a new electrostatic latent image developing device of a noncontact liquid developing system capable of excellently developing even the parts of a high image density and high resolution.
CONSTITUTION: Plural developing means composed of one set of developing rollers 20 and 24 disposed in close proximity to the surface of a latent image carrier 1 across a developing gap in a prescribed developing part and holding a thin film-like developing liquid on the peripheries and rotated in a prescrived direction, that is, rotated to impart the held developing liquid to a developing part and liquid film forming means forming a developing liquid film thinner than the developing gap, on the peripheries of the developing rollers by squeezing rollers 21 and 25 disposed in the proximity to the developing rollers 20 and 24 are arranged along the moving direction of the surface of the latent image carrier 1, to form a developing means train the developing liquid is supplied onto the peripheries of the developing rollers 20 and 24 in each developing means and the developing conditions of each developing means are set so as to attain development in at least two different kinds of developing conditions, in the developing means train.
