Abstract
An image forming apparatus has a photosensitive drum, a charger for uniformly charging a surface of the drum, an optical head for irradiating the surface of the drum with light to change a charging state of the drum surface, and a developing device for causing a toner to adhere on the surface of the drum in accordance with the charging state. The charger has a grid with two wire fixing portions each provided with two grooves, a first discharge wire fitted in one of the two grooves of each wire fixing portion, and a second discharge wire fitted in the other of the two grooves of each wire fixing portion. The two grooves of each wire fixing portion are arranged relative to the grid so that the first and second discharge wires are arranged parallel to one another along a substantial center in a width direction of the grid.
