PURPOSE:To form an image extending over many fields by combining and using a light source for oscillating a specific light and a photosensitive zone having sensitivity to its light and a toner, and a toner having an absorbing zone in a visible area. CONSTITUTION:A light source for oscillating a light beam of an infrared area to a visible, infrared or invisible light and a photosensitive zone having sensitivity against the above light and a toner, and a toner having an absorbing zone in a visible area are combined and used. This toner shows transparency against a light beam of the visible area, and has an absorbing zone in an infrared area, and when it is used, an image sensed only by a light source for oscillating a light beam of the infrared area can be detected. For instance, when an electrophotography device on which the light source for oscillating the light beam of the visible area, the photosensitive zone having sensitivity against the light beam of the visible area, and the toner having an absorbing body in the visible area are loaded is used, the visible image can be converted to an invisible image. By varying this combination, an image extending over many fields can be obtained. |
