Abstract
PURPOSE: To enhance transporatability, chargeability, fixability, etc., of a developer, by forming part of toner into a sphere and the other part into a shapeless form in a 2-component type developer consisting of magnetic and nonmagnetic toners.
CONSTITUTION: All or part of the nonmagmetic toner is formed into a sphere and the other part is formed into a shapeloss form in a shapeless form in a binary developer prepared by mixing the magnetic and nonmagnetic toners of both 3W50 μ, preferably, 5W30 μ average particle diameter in a mixing ratio of 100:3 to 100: 100 by weight. A desirable content of the spherical toner in the magnetic toner is about 10W70 weight %, preferably, 10W60 weight %.
