Abstract
A developing device including: a toner bearing member configured to bear a toner on a surface of the toner bearing member and configured such that the surface thereof is rotated to supply the toner to and develop a latent electrostatic image on a surface of a latent electrostatic image bearing member in a developing region which faces the latent electrostatic image bearing member; and a regulating member configured to regulate an amount of the toner to be moved towards the developing region, wherein the surface of the toner bearing member has regularly arranged convex portions, and wherein a non-electrostatic adhesive force between the toner and the surface of the toner bearing member is less than 9.0 nN.
