Effective Boltzmannians in the sense of the block spin renormalization group are computed for the 2D Ising model. The blocking is done with majority and Kadanoff rules for blocks of size . Transfer matrix techniques allow the determination of effective Boltzmannians as polynomials in for lattices of up to blocks. The zeros of these polynomials are computed for all non-equivalent block spin configurations. Their distribution in the complex -plane reflects the regularity structure of the block spin transformation. In the case of the Kadanoff rule spurious zeros approach the positive real -axis at large values of . They might be related to the renormalization group pathologies discussed in the literature.
