摘要： A developing apparatus for developping an electrostatic latent image includes a movable developer carrying member facing toward or contacted with an image bearing member in a developing zone. An elastic regulating member for forming a regulated developer layer on the developer carrying member is elastically urged toward the developer to form a nip therebetween, through which the developer is conveyed to the developing zone. Fine particles different from particles constituting the developer are arranged on the surface of the regulating member comprising the nip.
