PURPOSE:To control a printing material transport body with high precision by forming the holes having the less diameter than that of the toner for forming an image onto almost all the parts of a printing paper sheet conveyor belt onto which the printing paper sheet for the printing of the image formed in an image formation part is loaded and conveyed. CONSTITUTION:A printing material (paper sheet) onto which an image is printed is loaded onto a printing material conveyor belt 8 and transported in the direction of allow, and the image is printed onto the paper sheet and fixed. The belt 8 is joined at the seam 20, and an endless belt is formed, and transported by a main shaft roller 11 and a trailing roller 12, and the paper sheet is supplied by adjusting the timing by detecting the seam by a sensor 21, and an image formation part is started. The belt 8 is formed by using each cut part of a long sheet material which is made of high polymeric polyethylene and has a thickness of 100 mum, and the holes having the max. hole diameter of 15mum and the average hole diameter of 1mum which is less than that of toner particle are formed with the porosity of 70%. Therefore, the high speed control of the belt 8 with high precision is permitted, and the generation of the printing unevenness of the image is prevented.
