  In this paper we present the derivation as well as the numerical results for
all electromagnetic form factors of the nucleon within the chiral quark soliton
model in the semiclassical quantization scheme. The model is based on a
semibosonized 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 $400-420$
MeV.
