Abstract
An electrophotographic print marking apparatus for printing markings on rolled steel plates while the steel plates are being fed in a heated condition. A part of an image transfer belt which is brought to a transfer section where the powder image carried by the belt is transferred to the steel plate is made movable up and down by means of a pair of lower rollers. The rollers are moved up and down to bring the part of the belt in the transfer section close the steel plates when the powder image is transferred to the steel plates and to separate the belt far apart from the steel plates when the powder image is not transferred. A tension roller is provided to absorb the change in tension of the transfer belt accompanying the up and down movement of the lower rollers.
