An image forming apparatus includes a photosensitive drum, a charging roller, a development device, a transfer roller, a first electricity eliminator and a controller. The photosensitive drum is provided on a conveyance path along which a sheet is conveyed. The charging roller charges the photosensitive drum. The development device develops an electrostatic latent image formed on the photosensitive drum charged by the charging roller. The transfer roller faces the photosensitive drum across the conveyance path and generates a transfer bias. The first electricity eliminator irradiates the photosensitive drum with light on a downstream side of the development device in a rotational direction of the photosensitive drum and on an upstream side of the transfer roller in the rotational direction. The controller which controls the first electricity eliminator so as to irradiate only a non-sheet passing area of the photosensitive drum with the light.
