A two component-type developer for electrophotography showing improved electrophotographic performances and also free from carrier adhesion (undesirable carrier transfer to the photosensitive member and recording materials) is constituted by using a magnetic carrier comprising a soft magnetic material of 5-100 mu m in particle size. The carrier has a bulk density of at most 3.0 g/cm3, and magnetic properties including: a magnetization of 30-150 emu/cm3 under a magnetic field strength of 1000 oersted, and relationships (1) and (2): | sigma 1000- sigma 300|/ sigma 1000</=0.40(1) wherein sigma 1000 and sigma 300 denote magnetizations (emu/cm3) under magnetic field strengths of 1000 oersted (Oe) and 300 oersted (Oe), respectively, and 0.15 (emu/cm3xOe)</=| sigma 100-r|/100 (Oe)(2), wherein sigma 100 and sigma r denote magnetizations (emu/cm3) under magnetic field strengths of 100 (Oe) and zero (Oe), respectively. |
