<p>PROBLEM TO BE SOLVED: To provide an image forming device capable of realizing the excellent image quality by uniformly performing charge as well as improving a recovering performance for residual transferring toner on the developing device, realizing a long life by preventing crack on a photoreceptor, and restraining the image blurring, for developing and simultaneously cleaning system. SOLUTION: This tandem type image forming device is provided with the photoreceptor provided with a photosensitive layer on a conductive support, a charging means consisting of magnetic particles supported by a conductive support for charging the photoreceptor by being arranged in contact with the photoreceptor and applying voltage to the photoreceptor, a latent image forming means for forming the electrostatic latent image, a developing means serving as a cleaning means for forming the toner image by developing the electrostatic latent image and simultaneously recovering the transfer residual toner remaining on the photoreceptor after transferring, and a transferring means for transferring the toner image. In this case, the magnetic particles have a particle size distribution provided with two or more peaks or shoulders in a range of 0.5 to 200μm, average diameter of 10 to 50μm, aggregation degree of >=60%, and specific surface area of >=0.100 m2/g.</p> |
