Toner adhesion

Toners are comprised of a colorant in a resin binder. The colorant concentrations are typically 10%. Depending on the application, additional components may include additives to control the charge level, surface additives to control flow and cleaning, and/or waxes to prevent toner adhesion to the fuser roller. For black and white applications, the most common colorant is carbon black. The role of the resin is to bind the toner to the receiver, thus creating a permanent image. The choice of the resin depends on the fusing process. 

The demonstrated relationship between the presence of hydrocarbon and fuseability of toner to the paper is equally important to the paper manufacturers and to the toner/copier manufacturers. It is possible that modifications to the surface sizing process could provide better surfaces for toner adhesion.

Softening of the paper surface in fusing may cause adhesion on the counter roll, loosening particles from the surface and leading to accumulation on the rollers of the printer. Good toner adhesion requires surface-chemical compatibiHty of paper and toner. With an increase in the resolution of printing and the related decrease in toner size, the smoothness requirements of the paper surface become increasingly important...
