  The application of k_t - factorization, supplemented with the CCFM small-x
evolution equation, to heavy quark production is discussed. Differential cross
sections of b-b_bar production and also inelastic J/psi production as measured
at HERA are compared to the hadron level CCFM Monte Carlo generator CASCADE,
using the unintegrated gluon density obtained within the CCFM evolution
approach from a fit to HERA F_2 data.
