Abstract:
1. An image-forming apparatus comprising: an image-forming means for forming a toner image and for transferring it onto a recording medium by an electrophotographic system, a fixing means for heat-fixing the toner image onto the recording medium, a discharge conveying passage for conveying the recording medium onto which the toner image has been heat-fixed to a discharge portion, and an apparatus body wherein the image-forming means, the fixing means, and the discharge conveying passage are arranged, the apparatus body having a cooling structure including a right side wall and a left side wall positioned to face the right side wall at a distance, wherein at least one cooling fan for forming an air stream heading from the side of the image-forming means toward the discharge conveying passage is arranged facing the discharge conveying passage, and exhaust ports are formed in the discharge conveying passage facing the cooling fan, and ventilating ports for the air from the cooling fan are formed in the right side wall and/or the left side wall in the discharge conveying passage so that the air from the cooling fan is exhausted through the ventilating ports while the recording medium is transferred in the discharge conveying passage.
