Abstract

A development apparatus including a developer-bearing-member for developing latent electrostatic images formed on a latent-electrostatic-image-bearing member to visible toner images by the application thereto of a non-magnetic one-component developer including matrix toner particles and a fluidity-imparting agent; and a developer-thin-layer-regulating member for forming a thin layer of the non-magnetic one-component developer on the surface of the developer-bearing member, the developer-bearing member having a surface portion which is intermediate between the matrix toner particles and the fluidity-imparting agent in the triboelectric series thereof.
