Developing device and image forming device

A developing device for forming an image by developing an electrostatic latent image formed on an image carrier with a developer, the developing device comprising:

• a developing container that accommodates the developer;
• a developing roller that faces the image carrier, is disposed adjacent to the developing container, and conveys the developer accommodated in the developing container to the image carrier;
• and
• a developer discharging part that is provided in the developing container and discharges a part of the developer,
• wherein a discharge amount of the developer discharged by the developer discharging part is controlled on the basis of a charge amount of a toner included in the developer,
• wherein when the discharge amount of the developer is reduced in accordance with a decrease in the charge amount of the toner included in the developer accommodated in the developing container, as the charge amount of the toner included in the developer decreases, the discharge amount of the developer is increased.
