Japanese Patent JP7328026

B2

To prevent the occurrence of image deletion by performing current detection to maintain the amount of metallic soap on a surface of a photoreceptor.SOLUTION: An image forming apparatus has a current detection unit that detects a curent flowing from a charging member to an image carrier in a state where a charging voltage is applied to a voltage application unit and a control unit that controls the voltage application unit, and executes an image forming operation for forming a toner image on a recording material and an application operation for applying metallic soap to a surface of an image carrier by supplying a toner stored in a toner storage unit from a developing member to the surface of the image carrier. When a current value of a current detected by the current detection unit is a first current value, the image forming apparatus does not execute the application operation, and when the current value is a second current value with a larger absolute value than that of the first current value, executes the application operation.SELECTED DRAWING: Figure 7
