We investigate the properties of a dressed electron which reduces, in a particular class of gauges, to the usual fermion. A one-loop calculation of the propagator is presented. We show explicitly that an infrared 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 previous conjectures. © 1997 The American Physical Society.
