摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus which has an intermediate transfer body to which a developer image is electrostatically transferred from an image carrier at a primary transfer position, and a 1st residual developer electrifying means electrifying the residual developer to a specified polarity after the developer image is electrostatically transferred to transfer material from the intermediate transfer body at a secondary transfer position by the application of a alternating voltage, whereby the residual developer electrified to the specified polarity is electrostatically transferred to the image carrier from the intermediate transfer body at the primary transfer position, and in which in-machine soiling by toner scattering is prevented and which has sufficient cleaning performance for the residual toner on the intermediate transfer body even if it is much. SOLUTION: This image forming apparatus is provided with a 2nd residual developer electrifying means 25 for applying DC voltage between the secondary transfer position N2 and the 1st residual developer electrifying means 23 along the intermediate transfer body 9.

摘要： PROBLEM TO BE SOLVED: To provide a toner which can ensure sufficient developing property, without causing decrease in the life time of a developer carrying body, even if the process speed is increased, and to provide an image forming device and a process cartridge which use the above toner. SOLUTION: In the image forming device, the peripheral velocity of the photoreceptor is >=150 mm/sec, and the toner in the developer contains at least a binder resin and a magnetic material and has 5 to 12 μm weight average particle size. The toner used has properties with the particles of the toner having >=3 μm diameter calculated as circles in the toner contain particles, having >=0.900 circularity a by >=90% in terms of the cumulative value, based on the number and the toner satisfying the following conditions (a) or (b). (a) The cut rate Z and the weight average particle size X of the toner satisfy the relation Z =0.950 circularity based on the number, and the weight average particle size X of the toner are in the relation of Y>=exp5.51×X-0.645. (b) The but rate Z, X and Y satisfy Z>5.3×X and Y>=exp5.37×X-0.545.

摘要： PROBLEM TO BE SOLVED: To restrain shaving due to abutting of both ends of a photoreceptor against a transfer roll. SOLUTION: In the unit, the service life of the photoreceptor drum 1 can be prolonged by restraining the shaving in both end side regions of the photoreceptor drum 1, by making the fictional force between both end side regions (non-paper passing pat) of an elastic layer 4a of the transfer roll 4 and the photoreceptor drum 1 to be smaller than the frictional force between a central part region (paper-passing part) that is positioned inside these both end side regions and the photoreceptor drum 1 by polishing the central part region of the elastic layer 4a and the both end side regions (width t), where the length of the transfer roll 4 is L, by reversing the direction of polishing for each.
