PROBLEM TO BE SOLVED: To provide an image forming device making a power applying terminal continuously utilizable regardless of the wear of the power applying terminal by constituting the power applying terminal, replaceable the position brought into contact with the power receiving terminal. SOLUTION: A bar shape terminal 106 applying a developing bias is supported by a bracket 107 in freely rotatably with a rotary center position shifting outside of locus of the developing roller shaft 98a in consequence of rotation of a revolver developing unit. At the bias applying time, in the case disturbance occurring in the bias application, by the wear on a contact position S of a bar shape terminal held in contact with the developing roller shaft 98a, the image forming device is allowed to rotate the bar shape terminal by 180 degrees with the center at the shaft 1, and to make an area on the bar shape terminal surface out of wearing brought into contact with the developing roller shaft end part. |
