摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus and a paper feeding device which can consistently feed paper sheets, and preventing any trouble such as printing deviation, jamming, empty feed, and double feed.SOLUTION: A paper feed tray 31 stacks paper sheets P to be fed to an image forming part. Paper sheet elevating/lowering parts 35a-35f are provided to the paper feed tray 31 to partially elevate/lower the paper sheets P stacked on the paper feed tray 31. Unevenness detection sensors 34a-34f detect uneven states of the highest paper sheet P stacked on the paper feed tray 31. A paper feed determination part determines whether the paper sheet P stacked on the paper feed tray 31 can be fed to the image forming part based on the result of detection by the unevenness detection sensors 34a-34f. A control part adjusts the elevating/lowering positions of the paper sheet elevating/lowering parts 35a-35f by driving the paper sheet elevating/lowering parts 35a-35f when the paper feed determination part determines that the paper sheets cannot be fed to the image forming part. Thus, the paper sheets P stacked on the paper feed tray 31 are partially elevated/lowered to reduce the unevenness of the paper sheet P. As a result, the paper sheets P can be consistently fed to the image forming part.

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.
