Title: Method for automatic adjusting density of liquid developer
Inventor: KUWABARA SHIGEO
IPC: G03G15/10
Filed: 1982-02-24
Abstract: PURPOSE:To adjust the density of a developer with simple process, by determining beforehand the relation of the amt. of the developer in the stage of service limit and the change in density and detecting the change in the amt. of the developer. CONSTITUTION:The initial level L1 of a developer 2 in a developing tank 1 and the limit level L2 at which the developer 2 arrives when consumed by volume DELTAQ are beforehand set in a level detector 10. The level of the developer 2 falls gradually, and at the point of the time when the toner concn. therein decreases to D2, the developer arrives at the limit level L2, then the detector 10 detects the level L2 and opens a solenoid valve 7 so that the developer 2b for replenishing is supplied from a spare tank 1b into the tank 1. When the developer 2b is supplied by the volume DELTAQ and the level of the developer 2 arrives at the initial level L1, the detector 10 detects said level and closes the valve 7. At the point of this time, the limit toner density D2 of the developer 2 resumes the initial toner density D1. The density of the developer is thus adjusted with the simple process.
