ABSTRACT:
A ventilation device for a photocopier draws ozone mixed air from a developing unit and image transfer unit and forwards it to ventilate a fusion unit where the subsequent heating of the air reduces the ozone content. The air flow evacuates the condensed water issued by the sheets of paper during the fixing.
