Abstract: The invention achieves uniform image quality for every transfer regardless of a moisture content on a surface of a paper sheet when a plurality of transfer processes is to be made on a single paper. A copier (1A) is provided with a optical sensor (20) which includes at least one light source, illuminates a paper sheet (P) with light, receives the light reflected from the paper sheet (P), and measures the received light intensity. Before each of a plurality of transfer processes, the copier (1A) calculates a moisture content on a surface of the paper sheet (P) from the light intensity measured by the optical sensor (20), and sets a transfer condition of a transfer device (15) based on the calculated moisture content on the surface of the paper sheet (P).
