  The rates of inclusive photo- and electroproduction of the eta_c meson:
gamma* + p -> eta_c + X are calculated in the triple Regge region, integrated
over the diffractive mass X. For the Regge exchanges we use the hard Pomeron
and Odderon, both being calculated in the framework of perturbative QCD. The
integrated cross-section depends upon the coupling of the BFKL pomeron to two
$C=-1$ odderons, and it is found to be of the order 60 pb for photoproduction
and 1.5 pb at Q^2=25 GeV^2.
