Abstract
A charging device which charges a body to be charged. At least a pair of linear electrodes is provided on a substrate so as to be close to each other. Walls are provided near the linear electrodes. Each of the walls has a height larger than a line width of each of the linear electrodes. The linear electrodes are surrounded by the walls and the substrate. The charging device alternatively includes a plurality of dielectrics and electrodes disposed along a first direction facing a drum so that the plurality of dielectrics sandwich the plurality of electrodes along a second direction perpendicular to the first direction, the dielectrics have a height larger than a height of the electrodes along the first direction, and at least two neighboring electrodes have different shapes.
