An ultrasonic fuser for fixing toner images to substrates utilizes an acoustic transducer or resonator in the form of an ultrasonic welding horn and a viscoelastic member. As toner images carried on a substrate are moved between the resonator and the viscoelastic member heat energy is created both in the toner particles forming the images and the viscoelastic member. The heat energy created in the viscoelastic member is transferred to the toner images through intimate contact therewith and together with the heat generated in the toner serves to elevate the toner to its fusing temperature.
