Abstract
We investigate the properties of a dressed electron which reduces, in a particular class of gauges, to the usual fermion. A one-loop calcula tion:of the propagator is presented. We show explicitly that an infrar ed finite, multiplicative, mass shell renormalization is possible for this dressed electron, or, equivalently, for the usual fermion in the above-mentioned gauges. The results are in complete accord with previo us conjectures.
