摘要： A developer carrying member is provided which, even in continuous copying over a long term and also even under different environmental conditions, do not cause any charge-up of toner, and prevent the toner from melt-adherent to the developer carrying member surface and developer layer thickness control member surface to maintain the state of uniform coating of a developer having a toner and to make the toner uniformly and quickly triboelectrically charged, so as to obtain high-grade images free of any image density decrease, image density non-uniformity, sleeve ghosts, fog and vertical streaks during running service. Provided are a developer carrying member having a substrate and a resin coat layer on the surface of the substrate, which resin coat layer contains at least a binder resin and a carbon black, where the graphite (002) plane obtained from X-ray diffraction of the carbon black has a lattice spacing of from 0.3370 nm or more to 0.3450 nm or less; and a developing assembly having such a developer carrying member.
