| 摘要 | An image forming apparatus includes a pre-fixing sheet guide and a toner collection device. The pre-fixing sheet guide is to let a sheet conveyed along it, the sheet with a toner image transferred thereon at a transfer portion to an end part of the sheet. The sheet guide has a width shorter than a maximum printable sheet width. The toner collection device includes an adsorption member (pressure roller) that is disposed in the vicinity of the pre-fixing sheet guide and having a surface exhibiting conductivity, and a potential difference formation mechanism (earth mechanism) configured to form a potential difference between the surface of the adsorption member and the toner. | ||
