We consider electrical resistivity of ferromagnetic metals in which magnetism and electrical currents are carried by the same electrons of single bands. Relaxation times of electrons with up (or down) spin are expressed in terms of collision integrals by solving a coupled Boltzmann equation. We analyze Umklapp -as well as normal -processes of electron-electron scattering in Born approximation for ferromagnetic state. The coefficient of the quadratic term in temperature dependence of resistivity is found to decrease when magnetization develops at low temperatures.
