PROBLEM TO BE SOLVED: To prevent wear, deformation and damage of clearance forming members which form a clearance between a photoreceptor drum and a developing sleeve and to obtain a stable image output. SOLUTION: First clearance forming members 103a and 103b are provided on the same axis as a photoreceptor drum 7, and also second clearance forming members 106a and 106b which are in contact with the first clearance forming members 103 are provided on the same axis as a developing sleeve 9c. The outside diameter of the first clearance forming members 103a and 103b and second clearance forming members 106a and 106b is determined so that they can rotate without causing slip of contact parts of them. |
