A charge-eliminating device for eliminating charge of a sheet on which toner is fixed by an image forming apparatus includes a conveying guide, a first charge-eliminating unit and a second charge-eliminating unit. The conveying guide forms a conveyance passage through which the sheet conveyed from the image forming apparatus is conveyed. The first charge-eliminating unit is disposed on one side of the conveyance passage in a thickness direction of the sheet and eliminates charge of the sheet in a non-contact state with the sheet. The second charge-eliminating unit is disposed on the other side of the conveyance passage in the thickness direction and eliminates charge of the sheet in the non-contact state with the sheet.
