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.

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： The object of the invention is to certainly remove and certainly recover the charged toner remaining on a developing roller after development. A single component toner which is delivered to the developing roller via a toner-supplying roller is made into a relatively thin layer of a predetermined thickness with a charging plate and is frictionally charged with a given quantity of electric charge. Subsequently, the toner is adhered on a photoreceptor drum along by the electrostatic latent image to develop an image at the developing region at which the developing roller comes into contact with the photoreceptor drum. After development, the electric charge of the toner layer on the developing roller is removed with an electric-charge-removing sheet. The toner after development is recovered into a toner hopper via the toner-supplying roller. In rotation direction of the developing roller, the relation of the width Wt of the toner layer to the width Wc of the electric-charge-removing sheet is established so as to be Wc.gtoreq.Wt. Thus, the electric charge of the toner layer on the developing roller is certainly removed.
