Abstract: 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.

Abstract: In a cross section perpendicular to a rotational axis of a first image bearing member, when a common tangential line between the first image bearing member and a second image bearing member on an intermediary transfer belt side is a rectilinear line L, a rectilinear line passing through a rotation center of the first image bearing member and a rotation center of a first transfer member is a rectilinear line P, and a rectilinear line passing through an intersection point between the rectilinear line P and the first image bearing member and perpendicular to the rectilinear line P is a rectilinear line Q, an electrode member is constituted so that the contact portion contacting an inner surface of the belt is positioned on a first image bearing member side than the rectilinear line L is and on a first transfer member side than the rectilinear line Q is.
