Abstract
A total layer thickness detection apparatus for a charged body includes: a saturated charge amount detection unit that detects a saturated charge amount of a charged body having plural coating layers with mutually different relative dielectric constants; a storage unit that stores relation information indicating relation of change of the saturated charge amount of the charged body with respect to a change of layer thickness of a surface layer of the charged body; and a calculation part that calculates a total layer thickness of the plural coating layers of the charged body based on the change of the saturated charge amount detected by the saturated charge amount detection unit and the relation information stored in the storage unit.
