Within the framework of light-cone algebra, it is shown that a logarithmic divergence in the electromagnetic mass shift of a hadron arises precisely due to a mass term in the quark propagator. This divergence, therefore, can be removed by mass renormalization, The coefficient of this divergence is a scalar density which transform as S/sub 3/ for the case of a nucleon. In our analysis, the gauge invariance to order l/q/sup 2/ is explicitly used. (auth)
