An equiaffine space is a manifold $$A_n$$ with an affine connection whose Ricci tensor is symmetric. The authors study equiaffine spaces admitting an holomorphically projective map $$f: A_n\to K_n$$, $$K_n$$ denoting a Kähler space. Assume that the Ricci tensor of $$A_n$$ preserves the almost complex structure induced on $$A_n$$, via $$f$$, by the Kähler structure on $$K_n$$. If $$A_n$$ is semisymmetric, then $$K_n$$ is quasisymmetric or has constant holomorphic sectional curvature. Furthermore, if $$A_n$$ is a recurrent space, then $$A_n$$ is flat and $$K_n$$ has constant holomorphic sectional curvature.
