<P>PROBLEM TO BE SOLVED: To provide a substrate cooling method for efficiently cooling a substrate in an image forming apparatus of a type for feeding a recording material by air paper feeding. <P>SOLUTION: In the image forming apparatus which is provided with an endless porous feeding belt, uses an aspiration duct arranged inside the belt and forms an image by feeding the recording material to a prescribed image formation area while sticking the recording material to the porous feeding belt by aspiration via the porous feeding belt by the aspiration duct, the substrate stored in a substrate shield box attached inside the image forming apparatus is cooled by blowing exhaust air from the aspiration duct in the box via a paper powder filter. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
