A relativistic nonlocal model for the inclusive photoproduction of \ensuremathη mesons from complex nuclei is introduced. The model is based on the dominance of the S11(1535) resonance. We compare the results of our calculations with the available data on inclusive cross sections for the nuclei C, Al, and Cu. Assuming the resonance propagates freely in the nuclear medium, we find that the calculated angular distribution and energy dependence of the cross sections reproduce the data in a reasonable fashion. The present nonlocal model allows for the inclusion of density dependent mass and width in the calculations. Including these in the calculations and comparing with presently available data leads us to conclude that if any medium modifications of the properties of the S11(1535) resonance existed, they would likely be small.
