The cleaner may have a blade-like shape and may remove contaminants including residual toner from the photoreceptor. The charging mechanism may include a charging brush which may have a pile length not greater than 3 mm ... 06/08/06 - 20060120758 - Charging apparatus, process cartridge, and image forming apparatus A charging apparatus for electrically charging a member to be charged while magnetic particles is in contact to the member to be charged, includes a first magnetic particle carrying member for carrying the magnetic particles; a second magnetic particle carrying member for carrying the magnetic particles, the second magnetic particle ... 12/08/05 - 20050271419 - Charging device A charging device includes magnetic particles, a magnetic particle carrying member that magnetically carries the magnetic particles into contact with a member to be charged, and a magnetic particle adjusting unit for adjusting an amount per unit area of magnetic particles carried on the magnetic particle carrying member so that ... 06/30/05 - 20050141923 - Image forming apparatus The present invention extends the lives of a photosensitive drum and a cleaning blade. A magnetic brush charging device is excellent in charging performance, and is effective to realize being ozoneless and the smoothing of the photosensitive drum, and the removal of a fused material therefrom. However, due to the ... 06/23/05 - 20050135839 - Image forming apparatus and charging unit therefor An image forming apparatus includes an image bearing member, and first and second chargers. Each of the chargers includes a magnetic member for generating magnetism, has a holding member for holding magnetic particles by a magnetic force, and charges the image bearing member by bringing the magnetic particles in contact ... 06/16/05 - 20050129428 - Contact charger and image forming apparatus A contact charger for charging a charging target (e.g., a photosensitive member) includes a charging brush to be in contact with the charging target, and auxiliary charging particles to be interposed between the brush and the charging target. The auxiliary charging particle takes an acicular form having an aspect ratio ... ### FreshPatents.com Support - Terms & Conditions |
