As a first step towards the computation of the NLO corrections to the photon impact factor in the γ*γ* → γ* γ* scattering process, we calculate the one loop corrections to the coupling of the reggeized gluon to the γ*→ qq vertex. We list the results for the Feynman diagrams which contribute: all loop integrations are carried out, and the results are presented in the helicity basis of photon, quark, and antiquark.
