A developer regulating member provided in a developing apparatus includes a metallic thin plate. The metallic thin plate is provided with polyamide elastomer having a thickness of 5 to 300 mum at an abutment portion thereof with a developing roller. With the above structure, occurrence of a fused product is prevented, and a stable developer thin layer is formed. Accordingly, occurrence of a number of fine streaks on formed images is prevented, and thus, images of high quality can be obtained.
