  In this paper we present the derivation as well as the numerical results for
the electromagnetic form factors of the nucleon within the chiral quark soliton
model in the semiclassical quantization scheme. The model is based on
semibosonized SU(2) Nambu -- Jona-Lasinio lagrangean, where the boson fields
are treated as classical ones. Other observables, namely the nucleon mean
squared radii, the magnetic moments, and the nucleon--$\Delta$ splitting are
calculated as well. The calculations have been done taking into account the
quark sea polarization effects. The final results, including rotational $1/N_c$
corrections, are compared with the existing experimental data, and they are
found to be in a good agreement for the constituent quark mass of about 420
MeV. The only exception is the neutron electric form factor which is
overestimated.
