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.
