A fire prevention device for a fixing stage of an electrophotographic copying machine includes a heat shield plate movable to close the fixing stage. The heat shield plate may be controlled by a control mechanism having first and second solenoids so that the heat shield plate shuts the fixing stage only when a driving power for the copying machine is stopped or an abnormality is detected in a fixing step, during the copying operation.
