As it is well known, there are strong magnetic fields of orders 1012-1013 gauss and there are a lot of high energy free electrons and low frequency photons in the Universe. It is necessary to consider the inverse Compton scattering in intense magnetic field. Herold [7] has recently discussed the Compton scattering, in intense magnetic field for general case. In this paper, we have generalized his results to cases of the inverse Compton scattering, in which the initial electrons have very high velocities and the final electrons could be situated in any Landau excited states. We get the energy distribution of scattered photons for the most general cases (see equation (17)). The standard techniques of quantum electrodynamics are adopted. From the solutions of Dirac equation in homogeneous magnetic field, using exact propagator of electron in magnetic field and the relation, equation (21), given by Canute [10], we obtain scattering matrix elements, transition probabilities, genaral formulae for differential and total cross sections. The results could be applied to the mechanism of pulsar radiation.
