PROBLEM TO BE SOLVED: To provide a transfer device that obtains sufficient image density in a recess on a surface of a recording material without any burden.SOLUTION: A transfer unit 30 includes an intermediate transfer belt 31, a secondary transfer rear face roller 33, and a secondary transfer bias power source 39. The secondary transfer bias power source 39 applies a transfer bias formed by superimposing AC voltage on the DC voltage. The intermediate transfer belt 31 has at least one elastic layer. |
