  • Patent number: 9488929
    Abstract: An image forming unit suppressing occurrences of jitters, includes an image carrier rotating by drive force transmitted via a first route to form an electrostatic latent image, and a developer carrier having an elastic layer carrying a developer on a surface thereof and rotating by drive force transmitted via a second route to develop the electrostatic latent image. The electrostatic latent image is developed with the developer under a development condition that, with the elastic layer of a thickness from 0.5 mm to 2.5 mm, the developer carrier is rotated with a circumferential speed ratio to the image carrier in a range from 1.10 to 1.45, or that, with the elastic layer of a thickness more than 2.5 mm but not more than 5.0 mm, the developer carrier is rotated with a circumferential speed ratio to the image carrier in a range from 1.10 to 1.24.

  • Patent number: 7212755
    Abstract: A drum idle rotation is executed by the timing before printing on the basis of the number of drum idle rotating times selected by the operator, or the number of drum idle rotating times is set in accordance with a print image kind or a drum count value and the drum idle rotation is performed by the timing before printing on the basis of the set value. The number of drum idle rotating times by the timing before printing is corrected by a print density or an apparatus environment. Defective exposure or generation of a lateral stripe due to oligomer which is generated in the portion where a developing roller or a photosensitive drum is come into contact is prevented.

  • Patent number: 7058344
    Abstract: A developing apparatus supplies a developer from a developing roller to an image-bearing body that bears an electrostatic latent image thereon. A toner-supplying roller is rotatably supported to oppose the developing roller. A rotating body has recesses formed in its surface, opposing the developer-bearing member. The toner-supplying roller and the rotating body rotate in opposite directions and at different circumferential speeds. The rotating body is formed of a foamed material having cells formed in and open to a surface of the rotating body, the cells having a cell size in the range of 10 to 40 cells/inch. The toner-supplying roller and the rotating body rotate at circumferential speeds such that a ratio between the circumferential speeds is in the range of 1 to 2.5. The rotating body and toner-supplying roller may have a diameter that varies along the length.

  • Patent number: 7035561
    Abstract: An image to be formed on paper (26) is held on the surface of photo-sensitive drum (1). This is a latent image of static electricity formed by an LED exposer (5). Then, the developing roller (7) puts toner on the surface of photo sensitive drum (1), so as to develop a toner image. Meanwhile, the toner conveying roller (9) supplies toner to the developing roller (7). In this occasion, the printer controller (17) calculates the image density of image data (18) with dot counter (13). And, it decides the first voltage impressed to developing roller (7) by developing bias source (8) as well as the second voltage impressed to toner conveying roller (9) by stretching bias source (10) according to the image density of original image.
