IMAGE FORMING DEVICE AND IMAGE FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an image forming device capable of registering positions of images formed on both surfaces of transfer paper at high accuracy.

SOLUTION: The transfer paper P is conveyed in a direction of a conveying direction A before the image is transferred to a surface of the transfer paper P by an image formation part 60 and inclination to the conveying direction is corrected by abutting a side (first side) of a leading end on a register roller 43A. After the image is formed on the surface, the transfer paper P is reversed by an inversion passage 87 and an inversion conveying passage 88 and is conveyed in a direction of a conveying direction B. Inclination is corrected by abutting the side (first side) of the leading end on a register roller 43B. Thereafter, the transfer paper P is conveyed in a direction of the conveying direction A and the image is formed on the back surface without performing correction of inclination by the register roller 43A that time. The positions of the images formed on both surfaces can be aligned at high accuracy by correcting the inclination by abutting the same sides on the register roller 43A, 43B on the front surface side and the back surface side.
