Abstract (en)
An apparatus for conveying a transfer material (P) to a position where an image is transferred from an image bearing member (1) such an electrophotographic photosensitive member to it. A humidity detecting device (16) is provided in the image forming apparatus. An attracting device (6, 7) for electrostatically attracting the transfer material (P) on the transfer material conveying device (5). The attracting device is controlled in accordance with an output of the humidity detecting device. By this, the transfer material can be stably attracted on the carrying device irrespective of the humidity change in the apparatus. When the temperature is taken into account in addition to the humidity, a further preferable attraction control is possible.
