Abstract:
An image forming device includes a photosensitive member and a charger. The charger includes a wire electrode, a grid electrode and a shield electrode. The shield electrode including first and second ends facing the photosensitive member, the first end being disposed upstream of the second end in a moving direction of the photosensitive member, a shortest distance defined between a plurality of sections of the shield electrode and the wire electrode and being a length of a straight line that connects the wire electrode and an imaginary plane, the shortest distances between the sections of the shield electrode and the wire electrode being equal to one another, a first distance between the first end and a reference plane being smaller than a second distance between the second end and the reference plane, the reference plane including the wire electrode and extending perpendicularly to the photosensitive member.
