The developing applicator comprises a housing structure having two compartments divided by a partition wall. Within a first one of the compartments, there is provided an impeller and a supply roll assembly for transferrence of the developing material from the first one of the compartments to the other second compartment. Within the second compartment and adjacent the supply roll assembly, there is positioned a clipping roll assembly for clipping the developing material carried by the supply roll assembly. An applicator is positioned within the second compartment at a developing zone where the photoreceptor surface is moved. The applicator applies the developing material over the photoreceptor surface after it has received the developing material from the clipping roll assembly.
