A transparent film for electrophotographic image formation thereon is formed of a transparent substrate, and a surface-coating layer disposed on at least one surface of the transparent film. The surface coating layer is characterized by exhibiting a contact angle of 55-90 deg. with pure water at 23° C. and a humidity of 50%RH; containing an electronically conductive agent as a resistivity-adjusting agent; a universal hardness of at least 150 N/mm2; and exhibiting a surface resistivity of 1x108-1x1012 ohm/square. As a result of the specified properties, the transparent film exhibits good toner image transfer characteristic and provides images free from transfer failure, such as hollow image dropout, thin image density or discharge pattern formation.
