Abstract

Low smear toner compositions comprising mixtures of a microencapsulated toner formulation and a toner formulation without microencapsulation or nonmicroencapsulated for magnetic image character recognition (MICR) applications are disclosed. Magnetic image character recognition processes require a toner image to have both high toner fixing to paper and very low toner smear characteristics. A MICR toner composition which satisfies these requirements comprises a mixture of two toner formulations, one toner having high fix properties but less than acceptable MICR smear, the other toner having low smear properties but less than acceptable low fix levels. The resulting mixed toner composition utilizes the advantageous properties of each toner, that is, high fix and low MICR smear. An optimum developer mixture gives the desired properties of greatly reduced MICR smear with only a moderate decrease in the fix level of the toner.
