发明名称 Image forming apparatus having conductive sheet guide
摘要 An image forming apparatus includes a transfer portion transferring a toner image to a sheet, and a sheet guide portion guiding the sheet to the transfer portion. The sheet guide portion includes a resin member and a conductive member. The conductive member is provided to be in contact with the sheet to which the toner image is being transferred by the transfer portion and on a surface of the resin member so as to be grounded through the resin member, and has a volume resistivity which is lower than that of the resin member.

主权项 1. An image forming apparatus comprising: a transfer portion transferring a toner image to a sheet; a sheet guide portion guiding the sheet to the transfer portion, the sheet guide portion including: a resin member made of resin;a conductive portion provided to be in contact with the sheet to which the toner image is being transferred by the transfer portion, supported on the resin member, and electrically connected to the resin member, the conductive portion having lower volume resistivity than that of the resin member; anda ground portion configured to be electrically connected to the resin member to ground the resin member, wherein the conductive portion is grounded by passing current from the conductive portion, through the resin member, and to the ground portion.
