A toner layer regulating system for an electrophotographic image forming apparatus comprises a toner carrier; a metallic toner regulating member having a stress-strain curve prior to assembly with an elastic region, an inelastic region, and an initial yield stress value; and the toner regulating member supported in cantilevered fashion against the toner carrier so as to form a toner nip therebetween with an applied stress on the toner regulating member greater than the initial yield stress value. The metallic toner regulating member may comprise a metallic substrate and a coating thereon; the coating helping to form the toner nip. By deflecting the toner regulating member, when installed, by an amount that induces strains falling outside the elastic region of the corresponding stress-strain curve, the toner regulating system is less sensitive to geometrical variances.
