Abstract

This invention relates to a liquid development apparatus for use in an electrostato-graphic copier machine in which an electrostatic latent image on a photoreceptor is in a downwardly facing position and is to be developed with a liquid developer. Referring to the drawing, a liquid development apparatus 10 is located below a photoreceptor drum 11, which is mounted on a shaft 12 for rotation. Electrostatic latent images are formed on the surface of the photoreceptor drum 11 at process stations around the drum (not shown) and come to .the area of the liquid development apparatus 10 for development thereat. Although the photoreceptor is shown in the shape of a drum, other shapes (for example, an endless belt), which can present a downwardly facing latent image for development, are also suitable.

LIQUID DEVELOPMENT APPARATUS (Cont'd)

The liquid development apparatus 10 generally comprises a housing 13 for holding a column of the liquid developer therein. A piston means 14 is located inside the housing 13 and adapted to move in a vertical, reciprocating manner to selectively bring a column of liquid developer 15 in said housing into contact with the photoreceptor drum 11. The housing 13 has an inlet conduit 16 for the passage of liquid de...
