发明名称 Liquid developer supply device and image forming apparatus
摘要 Provided is a liquid developer supply device including plural accommodation tubs that respectively accommodate a liquid developer, a high concentration liquid developer, a dilution liquid and a standard concentration liquid developer, a first detection section that detects a solid component concentration of the liquid developer, and an amount of the liquid developer that is accommodated in the accommodation tubs, and a control section that controls the solid component concentration of the liquid developer to within the concentration range by supplying at least one of the high concentration liquid developer and the dilution liquid to an accommodation tub in which the liquid developer is accommodated based on detection results that are detected by the first detection section, and controls the amount of the liquid developer to greater than or equal to a predetermined amount by supplying the standard concentration liquid developer.

主权项 1. A liquid developer supply device comprising: a plurality of accommodation tubs comprising: (1) a liquid developer accommodation tub that accommodates a liquid developer that is used in image formation and includes toner as a solid component, wherein liquid developer is fed directly from the liquid developer accommodation tub to a developing device via a feed line from the liquid developer accommodation tub,(2) a high concentration liquid developer accommodation tub that accommodates a high concentration liquid developer in which a solid component concentration is higher than a predetermined concentration range,(3) a dilution liquid accommodation tub that accommodates a dilution liquid, and(4) a standard concentration liquid developer accommodation tub that accommodates a standard concentration liquid developer in which a solid component concentration is adjusted to a target concentration within a concentration range,wherein high concentration liquid developer feed lines allow the high concentration liquid developer to be fed from the high concentration liquid developer accommodation tub directly to the liquid developer accommodation tub and to the standard concentration liquid developer accommodation tub, and dilution liquid feed lines allow the dilution liquid to be fed from the dilution liquid accommodation tub directly to the liquid developer accommodation tub and to the standard concentration liquid developer accommodation tub; a first detection section associated with the liquid developer accommodation tub and that detects a solid component concentration of the liquid developer, and an amount of the liquid developer that is accommodated in the liquid developer accommodation tub; and a control section that controls the solid component concentration of the liquid developer to within the concentration range by supplying at least one of the high concentration liquid developer and the dilution liquid to the liquid developer accommodation tub based on detection results that are detected by the first detection section, and controls the amount of the liquid developer in the liquid developer accommodation tub to greater than or equal to a predetermined amount by supplying the standard concentration liquid developer from the standard concentration liquid developer accommodation tub to the liquid developer accommodation tub.
