  Processes of heavy quark photoproduction at HERA energies are considered
using the semihard (k_T factorization) QCD approach with emphasis of the BFKL
dynamics of gluon distributions. We investigate the dependences of the total
cross section of heavy quark photoproduction and also p_T, and rapidity
distributions on different forms of the unintegrated gluon distribution. We
present a comparision of the theoretical results with available H1 and ZEUS
experimental data for charm and beauty photoproductions.
