摘要： An image forming apparatus has a photoreceptor drum whereon a toner image is to be formed, a transfer drum for transferring the toner image to a transfer material by making the transfer material contact with the photoreceptor drum, the transfer drum having a dielectric layer, semiconducting layer and conducting layer laminated in this order from a surface which comes into contact with the transfer material, a power source section for applying any voltage to the conducting layer, and a grounded conducting roller which is located in an upstream section in a transfer material transporting direction with respect to a transfer position on a surface of the dielectric layer and comes into contact with the dielectric layer surface through the transfer material. The volume resistivity of the dielectric layer is not lower than 40 percent of the volume resistivity of the semiconducting layer. In this structure, a current component flowing in the circuit is greater than a current component causing the dielectric layer to function as a power source, thereby accumulating charges on the dielectric layer. As a result, stable adhesion of the transfer material to the transfer drum, and improved image quality are achieved.

摘要： A developing device prevents deterioration of toner, i.e., prevent the toner from being damaged, or fused onto the blade, to realize a more reliable developing operation. In the developing device, an electron emitting section is provided onto the toner regulation blade in which apertures (151) are formed, wherein each of the apertures (151) is formed by electroforming to have an inner surface curved convexly to be widened outwardly to the side irradiated with an ultraviolet ray (shape A). Further, a photoelectric surface (152) is laminated on the surface of the electron emitting section with the apertures (151). With an application of ultraviolet ray onto the electron emitting section, the resulting photoelectrons as emitted from the photoelectric surface (152) are guided to the toner through the apertures (151). Here, for the aperture (151) of the shape A, a larger amount of electrons can be guided to the toner than the apertures in other shapes (B to E).

摘要： The charging method is arranged so as to charge the toner on a developing roller by electrons as generated by the photoelectric effect from a photo-electric surface of a toner layer regulating/charging blade. An electric bias is applied across a toner layer thickness regulating/charging blade and a developing roller, and an amount of electrons discharged indicated by current flowing across the toner layer thickness regulating/charging blade and the developing roller is measured by an amplifier. When the amount of electrons discharged is detected to be 1/t of an initial amount, the amount of light to be received by the photo-electric surface of an ultraviolet ray luminescent is increased by t times to be the initial amount. According to the foregoing method, such event that the photoelectric effect is weakened due to the deterioration of the photoelectric surface can be detected with ease, and thus desirable charged state of toner can be maintained with ease.

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.
摘要翻译：根据本发明的调色剂和制造方法，通过将结合树脂组分溶解在粘合树脂组分中来制备由颗粒形状沉淀的粘合树脂组分和分散在粘合树脂组分中的着色剂组分的调色剂超临界流体（SCF），混合SCF中的着色剂组分，并降低粘合树脂组分在颗粒形状中沉淀粘结树脂组分的溶解度。即使着色剂含量增加，通过SCF，调色剂可以保持着色剂组分在颗粒形状中沉淀的粘合树脂组分中的分散性，同时也保持着色力。因此，调色剂可以促进使用调色剂的图像形成装置的小型化。
