Abstract:
1. A charging device for charging a member to be charged, comprising: magnetic particles; a magnetic particle carrying member that magnetically carries the magnetic particles into contact with the member to be charged, the magnetic particle carrying member having end regions in a longitudinal direction and a central region in the longitudinal direction; and a magnetic particle adjusting unit configured to adjust an amount per unit area of magnetic particles carried on the magnetic particle carrying member so that the amount per unit area of magnetic particles is larger in the end regions than in the central region, wherein the end regions of the magnetic particle carrying member are regions outside of a region of the member to be charged where an electrostatic latent image is formed in the longitudinal direction, and wherein the central region of the magnetic particle carrying member is a region inside the region of the member to be charged where the electrostatic latent image is formed in the longitudinal direction.
