PURPOSE:To obtain a toner having superior transferability on a sleeve, not causing scattering and also having superior fixability by using at least org. magnetic powder and a binding resin. CONSTITUTION:A toner is composed essentially of an org. magnetic body includ ing org. magnetic powder and a binding resin. The org. magnetic body has superior dispersibility in the binding resin, can provide weak magnetism to the toner and may be a known org. magnetic body such as iron (II, III)- polycarbene, preferably PPH.FeSO4. The binding resin may be acrylic resin having polar groups such as carboxyl, hydroxyl, glycidyl or amino groups. The toner has satisfactory fixability and does not cause scattering by which fogging, deterioration of image quality, unstableness of image density and con tamination in a copying machine are caused. |
