Wet Type Developing Apparatus

摘要

Abstract A wet type developing apparatus is disclosed which can eliminate the need to provide a separately built cleansing unit and, moreover, makes it unnecessary to dismount a developer supply unit for its cleansing operation and to perform its subsequent re-mounting operation. The apparatus in which a developing roller 2 is in rotational contact with a rotating photoconductor drum 1 and an electrostatic latent image made on a surface of the photoconductor drum is devel oped with a liquid developer 6 supplied onto the developing roller from a developer supply roller 3 whose surface is in part immersed in the liquid developer reserved in a developer reservoir 5, includes a cleansing arrangement, comprising a unit or units 7 and/or 8, which is disposed at a site in the developer reservoir which is always immersed in the liquid developer for cleansing a portion of the developer supply roller which is immersed in the liquid developer. __ - -_ FI G. i 5 6-'K
