Abstract
An image forming apparatus includes photoconductive drums aligned side by side for toner images in colors to be formed on peripheral surfaces thereof. A transfer belt turns while stretched over rollers for the toner images to be transferred thereon by being superimposed one another as a surface thereof abuts on the peripheral surfaces of the photoconductive drums. A transfer roller transfers the toner images from the transfer belt onto a recording sheet. The transfer belt uses the position of the transfer roller as a turning position and turns to have a first side that moves in a first direction towards the turning position while abutting the peripheral surfaces of the photoconductive drums and a second side that moves opposite to the first direction using the turning position as a starting point. A cooling mechanism cools the transfer belt by circulating taken-in outside air along a surface of the second side.
