摘要： A developing apparatus (4) has a developer supporting member 41 with a surface roughness R z in the rage from 3.0 to 5.5 µm and a one-component developer T with a bulk density in the range from 0.35 to 0.55g/ml, and an image is developed by forming a layer of the developer T on the developer supporting member 41. This makes it possible to form a thin toner layer stably despite changes in ambient conditions, and to prevent low image density and fogging. The absolute value of the amount of electric charge with which the developer T is charged is preferably in the range from 3.0 to 10.0 µC/g. The developer supporting member 41 is made preferably of stainless steel.
