    摘要： In a developing assembly including a two-component developer container and a developer-carrying member, 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 solid particles for making the resin-coat-layer surface uneven. The solid particles have an average circularity of 0.64 or more, which is the average value of the values calculated according to the equation Circularity=(4×A)/{(ML)2×Π}, (wherein ML represents the Pythagorean-method maximum length of a particle projected image, and A represents the projected area of a particle image), and the resin-coat layer has a surface roughness fulfilling specific conditions attributable to the solid particles. Also disclosed are an image-forming apparatus and a process cartridge which employ the developing assembly.
