PROBLEM TO BE SOLVED: To obtain an excellent image free from the image defect by preventing the separation discharge or the abnormal discharge from occurring in primary transfer nip parts. SOLUTION: This image forming device is, let respectively adopting elastic transfer blade in the plate shape 40, 41, 42 and 43, whose resistance is adjusted so as to become 1×101 to 1×1012Ωcm, as a primary transfer bias applying member which abut on the rear side of an intermediate transfer belt 5 in the primary transfer nip part N so as to bring the surface side of the belt 5 into contact with photosensitive drums 1a, 2a, 3a and 4a and apply the primary transfer bias onto the belt 5. In such a manner, an area where the electric field is effected by the primary bias in the vicinity the primary transfer nip part N is narrowed.
