If, in a standby state, no operation is executed for a control panel or ADF before the elapse of a predetermined time measured by a timer, the set temperature of a fixer is reduced. The region to be corrected then has a value of a pixel binarized in accordance with a third algorithm and replaced with the binarized value. In order to indicate the actions employed in the processing of the data to be transmitted, the transmitting device includes in the frame to be transmitted a predetermined number of control bits, the value of said control bits indicating how the transmittable data contained in the frame is processed prior to transmission. The work function layer may include alternating sets of titanium layers and sets of aluminum layers, thereby forming a nanolaminate structure.
