The surface voltage decay of a corona charged layer of TC22 (an ester of dehydroabietic acid and a hindered phenolic alcohol) is analyzed at different temperatures. Two relaxation processes are observed: a lower temperature process which can be related to the glass transition temperature and a higher temperature effect which can be related to the melting point. By considering the initial surface voltage and the quantitative effect of each relaxation on the total decay, the detrapping of shallower surface traps for the lowest temperature relaxation process and the detrapping of deeper bulk traps for the highest temperature relaxation are proposed as an explanation of the experimentally observed characteristics.
