PROBLEM TO BE SOLVED: To discontinue an image forming operation in the case printing paper is not carried a specific quantity, thereby avoiding an abnormal condition, and, furthermore, to prevent soil on the back of the printing paper. SOLUTION: In a transfer device which is equipped with a photoreceptor belt 1, for transferring a toner image, in a direction orthogonal to the direction of the supply carrying of the printing paper 9 and sets a carrying stroke for the printing paper 9 in relation to the area of image formation by the photoreceptor belt 1, paper-carrying quantitative detection sensors 12a and 12b for detecting a quantity of the carrying of the printing paper 9 is provided further downstream than the photoreceptor belt 1 in the direction of the carrying of the printing paper 9. Thus, the operation of transferring and the operation of feeding the printing paper 9 are discontinued in the case the quantity of the carrying of the printing paper 9 is not satisfactory. |
