Developer carrying member and developing apparatus

摘要

In a developer carrying member used in a developing apparatus by means of which an electrostatic latent image formed on an electrostatic latent image bearing member is developed with a developer to render it visible, the developer carrying member has at least a substrate and a resin coat layer formed on the substrate surface, and the resin coat layer contains at least a binder resin and graphitized particles. The surface of the resin coat layer has an average value A and a standard deviation sigma of 100<=A<=800 (N/MM²) and sigma<30 (N/MM²), respectively.
