METHOD AND DEVICE FOR IMAGE FORMING

PURPOSE:To view a high-grade image from the back surface of an OHP sheet by forming a latent image corresponding to the erected image of an original image on a latent image carrier, and transferring an image obtained by means of developing the latent image on the OHP sheet. CONSTITUTION:In an OHP mode, an electrostatic latent image formed on a photosensitive drum 1 is developed by a developing device 16, and transferred on the OHP sheet, and a toner image is fixed through a fixing device 22, so that the mirror image of the original image is formed on the OHP sheet. Therefore, when this image is viewed from the back surface of the OHP sheet having smoothness and high gloss, the erected image having a high image density and a high grade, can be viewed, and the developed image on the OHP sheet is viewed from the surface opposite to the developed image surface, having high smoothness and uniform gloss compared with the developed image surface of the OHP sheet, so that the image having the high image density and high grade can be obtained.
