<p>An image forming apparatus includes an image bearing member for bearing an electrostatic latent image; a developing container; a developer carrying member, including a first electrode member, for carrying the developer contained in the developing container to develop the latent image; a developer supplying member, including a second electrode member, for supplying the developer contained in the developing container to the developer carrying member by rotation in contact with the developer carrying member; a measuring portion for measuring a pixel number of an image to be formed; a supplying device for supplying the developer to the developer supplying member on the basis of a measured pixel number after image formation; and a detecting device for detecting an amount of the developer contained in the developing container by detecting electrostatic capacity between the first and second electrode members after the supplying operation.</p> |
