IMAGE FORMING APPARATUS

PROBLEM TO BE SOLVED: To provide an image forming apparatus that can prevent an image forming part and a fixing device from getting wet even when a liquid splashes to an upper part of an apparatus body.SOLUTION: A space 42 that communicates the inside and outside of a body casing 2 is formed in a paper discharge tray 27, provided on the top of the body casing 2, so as to be disposed between an image forming part 4 and a fixing device 20 when projected vertically. A rear through hole 68R is formed in a first lower wall forming member, provided between the image forming part 4 and the fixing device 20 to form a first conveyance path of paper P from the image forming part 4 to the fixing device 20, so as to vertically face the space 42. A liquid splashing onto the paper discharge tray 27 is made to flow downward of the image forming part 4 and the fixing device 20 so as to pass through between the image forming part 4 and the fixing device 20 through the space 42 and the rear through hole 68R.
