Abstract

Flash fusing of toner images depends on the absorption of the incident radiation by the toner and the subsequent flowing of the heated toner particles to either coalesce or penetrate into the upper fibers of the paper. Both of the foregoing phenomena are impeded by an image layer in which the toner particles are not in maximum contact with each other or with the paper. There have been suggestions to increase the packing density of the toner by the use of roll pressure prior to or during flash fusing Increased packing density can also be effected by charging the imnge layer to prior to flash fusing, charging being effected by exposing the image layer to a corotron or similar type device.
