  We study the possibility of low scale leptogenesis along with dark matter
(DM) in the presence of primordial black holes (PBH). For a common setup to
study both leptogenesis and DM we consider the minimal scotogenic model which
also explains light neutrino mass at radiative level. While PBH in the mass
range of $0.1-10^5$ g can, in principle, affect leptogenesis, the required
initial PBH fraction usually leads to overproduction of DM whose thermal
freeze-out occurs before PBH evaporation. PBH can lead to non-thermal source of
leptogenesis as well as dilution of thermally generated lepton asymmetry via
entropy injection, with the latter being dominant. The parameter space of
scotogenic model which leads to overproduction of baryon or lepton asymmetry in
standard cosmology can be made consistent in the presence of PBH with
appropriate initial mass and energy fraction. On the other hand, for such PBH
parameters, the DM is constrained to be in light mass regime where its
freeze-out occurs after PBH evaporation.
