Abstract
A discharger includes a discharging member that faces a member to be charged and discharges electricity by applying voltage; and a grid member that is disposed between the discharging member and the member to be charged and regulates electric discharge from the discharging member. The grid member has holes with a predetermined shape and extending through the grid member from the discharging member toward the member to be charged, and has a first region with the holes arranged at a first inclination angle, a second region with the holes arranged at a second inclination angle, and a boundary between the first and second regions and extending in the extending direction of the discharging member. When the first region is symmetrically projected onto the second region with respect to the boundary, an arrangement pattern of the holes in the first region and an arrangement pattern of the holes in the second region are positionally displaced relative to each other.
