Abstract
The generator QEDPS, a parton shower model in QED, developed by the present authors has been improved. By a careful study on the shower algorithm it was found that some finite contributions have been missed in the original version. They are small, but cannot be neglected when the contribution of the soft photons is dominant. A method is presented to correct these finite pieces and then a new generator, improved QEDPS, is proposed, which is able to make more precise prediction for the processes observed in e+e- annihilation as far as the initial radiation is concerned.
