Abstract
A heater comprises a substrate and an electrically conductive heating section having branched portions on its lateral edge. The heating section has notches at those portions of its lateral edges that are opposite to the branched portions. The notches increase electric resistance of the heating section at the branched portions to enhance heat generation of the heating section at the branched so that the heating section is heated at a predetermined temperature over the entire length of a transfer paper sheet.
