摘要： A discharging member includes an electrically conductive knit fabric, a support member, and a first magnet member. The conductive knit fabric is knitted into a cylindrical shape with use of yarn formed by twisting together a plurality of metal fibers. The support member is cylindrical shaped and inserted in the conductive knit fabric. The first magnet member is placed inside the support member. With the conductive knit fabric grounded or with a voltage applied to the conductive knit fabric, the discharging member is placed in noncontact with a discharged member in such a fashion that the first magnet member is opposed to the discharged member with the support member and the conductive knit fabric interposed therebetween.

摘要： 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 therewith. The magnetic member of each of the chargers has a magnetic pole facing the image bearing member. The second charger is located at the tail end in the image bearing member rotational direction, but before a position at which an image is formed on the image bearing member. In the image bearing member rotation direction, and relative to a position at which the image bearing member comes closest to the holding member, the first charger's magnetic member has a peak magnetic force positioned downstream, and the second charger's magnetic member has a peak magnetic force positioned upstream.
