Filed: 1990-09-05
Abstract: PURPOSE:To obtain an electrophotographic toner of a lower toner consumption quantity while it maintains a practically sufficient image density and a less fogging for the base by specifying the volume resistivity of the toner and a dynamic resistivity of the developer. CONSTITUTION:For the toner constituting the developer, a binder resin, a charge control agent, a coloring agent and other additives at need are mixed, melted and kneaded, then cooled, solidified, subsequently pulverized, and classified, then the toner is obtained. The dynamic resistivity of the developer consisting of the toner and a carrier, is defined as 1.0 X 10<11> - 3.0 X 11<11>OMEGA.cm and the volume resistivity of the toner is also defined as 1.0 X 10<10> - 4.0 X10<11>OMEGA.cm. By setting like this, the development property to the photosensitive body is enhanced even when an edge effect at a black solid part is generated and the proper image density is secured. Namely by specifying the dynamic resistivity of the developer, the proper edge effect is formed and with the toner of a lower volume resistivity, the image density is secured. Hence while the proper image density for the black solid part is secured, the excess toner consumption at the development stage is eliminated.
