    摘要： A developer carrying member and a developing assembly are provided which can stably provide the toner with triboelectric charges, may less cause any problems such as image density decrease, density non-uniformity and spots around images even during running on a large number of sheets, and can enjoy a stable and good developing performance. The developer carrying member has a substrate and a resin layer, and the resin layer containing a thermosetting resin, an acrylic resin having specific units and electroconductive particles.

    摘要： A developing apparatus is provided which can suppress a fluctuation in image density in a discontinuous printing mode provided with a pause period. The developing apparatus includes a developer for developing an electrostatic latent image on a photosensitive drum, a developer bearing member for carrying and conveying the developer and a developer layer thickness-regulating unit placed close to the developer bearing member for regulating the amount of the developer carried and conveyed by the developer bearing member, the developer layer thickness-regulating unit being. As the developer, a negatively chargeable, one-component, magnetic toner is used having magnetic toner particles containing a binder resin and a magnetic iron oxide particle, and has a specific saturation magnetization, specific weight-average particle diameter and specific composition. The developer bearing member includes a surface layer containing a binder resin, a quaternary ammonium salt, graphitized particles, and conductive, spherical resin particles, and has a specific surface shape.
