The consideration is based on universal unintegrated gluon densities, which have BFKL behavior in the small x region. Predictions of the CCFM evolution equation for D^* production are obtained and show a good description of D^* data at HERA.Latex 8 pages, 4 pagesHigh Energy Physics - Phenomenologytext
