The formalism of hyperquantization is applied to the quantum electrodynamics of a spin 1/2 field. The result is a gauge invariant theory containing an operator S whose matrix elements agree with those of the conventional S-matrix, but in which the use of the indefinite metric can be avoided. Dyson's equations and the generalized Ward identity are derived within this formalism.
