摘要： On surfaces of insulating layers 1b and 1c of a transportation member 1, a protective layer 1d having a volume resistivity of 1010 Ω·cm to 1017 Ω·cm is so laminated that a sum of thickness of the insulating layers 1b and 1c is less than intervals between adjacent ones of progressive wave generating electrodes 2. With this arrangement, it is ensured that a progressive wave electric field generated by the progressive wave generating electrodes 2 is exposed beyond a surface of the transportation member 1. Even if developer T and the transportation member 1 contact each other, a surface potential of the transportation member 1 is not changed. Moreover, firm adhering of the toner T to the surface of the transportation member 1 is prevented. It is therefore possible to certainly transport the developer T to a development position always stably.

摘要： According to a toner and a manufacturing method of the present invention, the toner, which is composed of a binding resin component precipitated in particle shapes with a coloring agent component dispersed in the binding resin component, is produced by dissolving the binding resin component in a supercritical fluid (a SCF), blending the coloring agent component in the SCF, and lowering solubility of the binding resin component for precipitating the binding resin component in the particle shapes. Even when the coloring agent content is increased, by the SCF, the toner can maintain dispersibility of the coloring agent component in the binding resin component precipitated in the particle shapes, meanwhile coloring power is also maintained thereby. Therefore, the toner can promote miniaturization of an image forming apparatus using the toner.
