Abstract
A fixing device includes a first fixing member, a second fixing member, and a charge application portion. The first fixing member contacts unfixed toner on a sheet conveyed along a conveyance path. The second fixing member forms a nip portion between itself and the first fixing member such that the sheet passes through the nip portion. The charge application portion applies an electric charge to the unfixed toner on the sheet and to an outer circumferential surface of the first fixing member at a region on an upstream side of the nip portion in a movement direction of the outer circumferential surface, by causing a corona discharge to be generated between a discharge electrode and a counter electrode that are disposed apart from the outer circumferential surface of the first fixing member.
