Image forming device

Abstract

Abstract PURPOSE:To improve the sensitivity of a photosensitive body and prolong its life, and speed up the fixation of an image by providing a heating part which preheats a body to be transferred. CONSTITUTION:Transfer paper 14 is coneyed through a conveyance path 8 and heated almost to melting point (80-120 deg.C) of toner by a heat roller 9 in the middle of the conveyance. This heated transfer paper 14 is sent to betweeen a photosensitive body 1 and transferring and peeling chargers 4 and 5 after development is performed by a developing device 3 by supplying the toner (a) to transfer the image on the photosensitive body 1 to the transfer paper 14. Then, the transfer paper 14 after the image is copied is conveyed by a conveyor belt 12, heated almost to a Gaussian transition point, and sent to a fixing roller 13. This fixing roller 13 fixes the image and the transfer paper is discharged. The transfer paper 14 is preheated by the heat roller before the image is transferred to the transfer paper 14, so the fixation is carried out excellently.
