  Previous results on form factors for the scaling Ising and the sinh-Gordon
models are extended to general $Z_{N}$-Ising and affine $A_{N-1}$-Toda quantum
field theories. In particular result for order, disorder parameters and
para-fermi fields $\sigma_{Q}(x), \mu_{\tilde{Q}}(x)$ and $\psi_{Q}(x)$ are
presented for the $Z_{N}$-model. For the $A_{N-1}$-Toda model all form factors
for exponentials of the Toda fields are proposed. The quantum field equation of
motion is proved and the mass and wave function renormalization are calculated
exactly.
