Abstract

Disclosed and shown in Figures 1 and 2 is an apparatus that enhances the cohesiveness of an image transferred from a photoreceptor or an intermediate source to paper or another substrate in electrophotographic printing machines. The disclosed apparatus use an ultrasonic energy device 4 to heat a narrow band of toner on photoreceptor 5 before (as shown in Figure 1) or while (as shown in Figure 2) transferring and fixing latent image 6 to substrate 7 with pressure transfix roll 8. Damper 10 localizes vibrations created by the ultrasonic device to the narrow band of toner. The ultrasonic energy device 4 includes an oscillator, a transducer to convert electrical oscillations to mechanical vibrations and an applicator or horn to transfer the mechanical vibrations to the photoreceptor. The disclosed toner transfer apparatus contrasts conventional apparatuses that transfer and then fix a latent image to a substrate using an internally heated fuser roll.
