ABSTRACT:
A developing device for developing an electrostatic latent image formed on an electrophotographic photosensitive member includes a rotatable developer bearing member bearing a developer thereon, a developer regulating member for regulating the amount of the developer born on the developer bearing member, a first rotatable developer conveying member for conveying the developer toward the developer bearing member, and a second rotatably developer conveying member. A developer-remaining-amount detecting member for detecting the amount of remaining developer is disposed in an area defined by the tangential lines of a first circle and a second circle as the loci of rotation of the first developer conveying member and the second developer conveying member as viewed from the longitudinal direction of the developer bearing member.
