Abstract : An approach to the removal of divergences in quantum electrodynamics id developed which employs 'dressed' particles throughout in place of 'bare' particles. This is done through replacement of the familiar creation-annihilation operators by 'source functions.' The question of whether source functions can be found which supply suitable solutions to simple problems is studied. First a method for normalizing the Feynman amplitudes is proposed, and tested by consideration of the second-order electron selfenergy. This quantity, logarithmically divergent on the usual theory, is found to converge for suitably chosen source functions. Next, the convergence of the charge renormalization constant for vacuum polarization is established for free photons. The requirements for a like result for virtual photons are indicated briefly.
