PURPOSE:To make fixing by a heating roller possible by using a toner contg. release components in making a master for xeroprinting. CONSTITUTION:Photosensitive paper 10 is wound on a drum and is subjected to electric charging by an electric charger 4, exposure of original images by a lens 2, developing by a developing device 5, and fixing by a fixing device 7, whereby a master fixed with the toner images on the photosensitive paper is made. Thereafter, the processes of electric charging, uniform exposure and developing of the master, transfer to copying paper 11 by a transfer device 6 and fixing of the transferred toner images by a fixing roller 9 are reiterated, whereby a copy 12 is obtained. If an infrared ray lamp is used as a fixing device 7, the electric charge holding capacity of the photosensitive paper will be decreasd by heat, and if a heating roller is used, antioffset liquid is requird, and therefore irregular fixing occurs. However, the antioffset component is included in the toner and therefore, the fixing having no irregularities by the heating roller is made possible. |
