Abstract

A printing or copying apparatus is provided having a thermofixing device for fixing a toner image to a sheet recording medium or substrate, such as paper. The apparatus has at least one cooling device operable to cool the substrate after it passes through the thermofixing device and before the substrate is stacked. The cooling performed by the cooling device prevents the toner image from undesirably sticking to an adjacently overlying substrate surface after stacking.
