<P>PROBLEM TO BE SOLVED: To prevent the end of the opening of a developing device from being soiled by reinforcing a sucking air current at the end of the opening of the developing device in a toner scattering preventing device generating the air current to suck air on the periphery from the opening of the developing device by the suction of the air from the developing device. <P>SOLUTION: This toner scattering preventing device in the image forming apparatus equipped with the developing device 14 developing a latent image to a visible image by sticking toner to a latent image on an image carrier 12 is provided with an exhaust means for exhausting the air from the upper part in the developing device 14 through an exhaust path 71. By sucking the air from the developing device, the air current to suck the air on the periphery from the opening 95 of the developing device is generated and also the suction port of an exhaust path 83 in the developing device is provided on the outside from image forming width, so that the air is directly sucked from the end of the developing device and the sucking air current at the end of the opening is reinforced, and the end of the opening of the developing device is prevented from being soiled. <P>COPYRIGHT: (C)2003,JPO |
