a developer carrier that supplies the component developer; a developer replenishment member that supplies the developer stored in the developer storage portion to the developer carrier; and a developer supply member that supplies the developer to the developer carrier. In the developing device, the developer regulating member is configured to thin the developer supplied and adhered to the developer to a predetermined thickness and to control the developer to have a predetermined charge amount. a first developer regulating member for uniformizing the amount of charge of the developer deposited on the body; and a layer of the developer whose charge amount has been made uniform by the first developer regulating member to a predetermined uniform thickness. , and a second developer regulating member that controls to provide a predetermined uniform charge amount. 2. The first developer regulating member and the second developer regulating member are each formed of a roll-shaped member that comes into contact with the surface of the developer carrier, and the first developer regulating member is provided with developer. A bias voltage having an AC component is applied to uniformize the amount of charge, and a DC bias voltage is applied to the second developer regulating member to adjust the amount of charge of the developer. A developing device according to claim 1 of the utility model registration claim. 3 The first developer regulating member is disposed downstream of the developer replenishing member in the conveying direction of the developer carrier, and the second developer regulating member is disposed downstream of the first developer regulating member. A developing device according to claim 1, characterized in that: 4. The developer carrying member is made of an elastic body, and the developer supply member and the first developer regulating member disposed in contact with the developer carrying member are also made of an elastic body,
The second developer regulating member is made of a rigid body, and a scraper for removing the developer adhered to the second developer regulating member is pressed into contact with the second developer regulating member. A developing device according to claim 1 of the utility model registration claim.
