PROBLEM TO BE SOLVED: To stably obtain an excellent image being free from a density gradient or the like, in an image forming device capable of feeding developer from one hand of transporting parts severally arranged on upper and lower position across a bulkhead to the developer transporting member, and then recovering the developer to the other hand of transporting parts. SOLUTION: This device is composed that two of transporting parts 13a and 13b for transporting the developer inside the device main body 10 is respectively arranged on the upper and lower positions across the bulkhead 14, so as to be confronted with the developer transporting member 11 for performing development by transporting the developer onto the image carrier 1, then the developer is supplied from one hand of the transporting part to the above mentioned developer transporting member, and the developer after developing is recovered from the developer transporting member by the other hand of transporting part. In this case, two circulation openings 14a and 14b through which the developer is circulated, is severally provided on each end part of the bulkhead, located in-between the two transporting parts, and in the same time at least, one more circulation opening 14c is disposed in the middle part of the bulkhead. |
