摘要: A two-component developer for electrophotography includes a toner comprising particles and an external additive composed of compound imidazole series or derivative. The has volume median particle size below that the particles, 0.1 to 100 μm. amount is 0.001 5% by weight based on particles. As result, scattering may be prevented formation fog in background reduced. In addition, electrostatic charge characteristics improved rises satisfactory manner.
