The orbital ferromagnetism of the itinerant-electron system with imaginary order parameter is studied at T=0 and T 0. The ferromagnetic ordering appears defined by the interband transitions with respect to the angular momentum. The expression for the magnetic susceptibility is obtained as functions of the modulus of the imaginary gap and of the square of the matrix element of the angular momentum.
