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 of 5 - 100 µm in particle size. The carrier has a bulk density of at most 30 g/cm³, and magnetic properties including: a magnetization of 30 - 150 emu/cm³ under a magnetic field strength of 1000 oersted, a magnetization (residual magnetization σ r ) of at least 25 emu/cm³ under a magnetic field strength of zero oersted, a coercive force of less than 300 oersted, and a relationship of:

|σ₁₀₀₀-σ₃₀₀|/σ₁₀₀₀ ≦ 0.40

wherein σ₁₀₀₀ and σ₃₀₀ denote magnetizations under magnetic field strength of 1000 oersted and 300 oersted, respectively.
