Podolsky's electromagnetism which explains some of unresolved problems of usual QED has been investigated in the framework of finite field-dependent (FFBRST) BRST transformation. In this generalized QED (GQED), BRST invariant effective theories are written using generalized Lorenz gauge, and no mixing gauge condition , and it contains higher-order derivative terms. No mixing gauge is free from UV divergences in the radiative correction and easier to handle. We construct appropriate FFBRST transformation to obtain generating functional in no mixing gauge from that in Lorenz gauge. We show that all these BRST invariant effective theories in GQED are basically the same and are inter-connected with appropriately constructed FFBRST transformations.
