摘要： An image forming device includes an image holding member and a charging unit. In a case in which an AC current, while being increased, is supplied to the charging unit in a state in which a DC voltage value and an AC voltage value applied to the charging unit are maintained, or a case in which a DC voltage, while being increased, is supplied to the charging unit in a state in which the AC voltage value applied to the charging unit is maintained, a current detection unit detects DC current values. An inflection point derivation unit derives an inflection point of a correlation line representing an correlation between the detected DC current values and the supply amounts. An execution unit executes pre-specified processing when a characteristic value of the derived inflection point reaches a pre-specified value.
