| Zusammenfassung: | An image forming apparatus includes an image bearing member, a developer carrying member, and a cleaning member including an elastic blade and a regulating portion. When an average of a free length L1 [mm] of the elastic blade in the image bearing region in the widthwise direction of the elastic blade is an average free length L1a [mm], an average of a free length L2 [mm] of the elastic blade on an outside of the developing region in the widthwise direction of the elastic blade is an average free length L2a [mm], and an absolute value of a difference between the average free length L1a and the average free length L2a is a free length difference ΔL [mm], the following relationships are satisfied:L2a ≥1.2×L1a,L2≥L2a−ΔL×0.2, andL1≤L1a+ΔL×0.2. |
