ABSTRACT:
A method for detecting a toner concentration of a developer including toner particles provides that when developing a latent image having a predetermined area formed on a photoconductor using a developing member, a developing current flowing through the developing member is detected, and the toner concentration is calculated directly from the detected developing current and the predetermined toner developed area of the latent image obtained by counting toner dots in the predetermined area.
