Abstract: An image forming apparatus includes an image forming portion configured to form a toner image on a recording material; a fixing portion configured to fix the toner image on the recording material by heating the toner image formed on the recording material; a flow path including a first space connecting with the fixing portion and a second space connecting with the first space and through which air discharged from the fixing portion passes; a first electrode portion provided in the first space and provided with a first potential; and a second electrode portion provided in the second space and provided with a second potential different from the first potential. An air speed of the air passing through the second space is slower than an air speed of the air passing through the first space.

Abstract: An image forming apparatus includes an image forming unit to form an image on a sheet, a conveyance guide unit, and a conveyance unit. The conveyance guide unit conveys the sheet on which the image is to be formed by the image forming unit. The conveyance unit conveys the sheet toward a first conveyance guide unit. The conveyance guide unit includes an urging member, a rotary member to be urged by the urging member and to rotate while abutting the sheet, a holding unit holding the urging member and the rotary member, and the first conveyance guide unit that is detachably attached to the holding unit to guide the sheet. The first conveyance guide unit includes a pressed portion, and the pressed portion is to be pressed by the sheet conveyed by the conveyance unit and has strength less than strength of the holding unit.

Abstract: A conveyance apparatus includes a change conveyance unit. In a case where a first sheet in a sheet storage unit included in the feeding apparatus is fed in a landscape orientation to the conveyance apparatus, the change conveyance unit changes a conveyance orientation of the first sheet to a portrait orientation. The landscape orientation is an orientation in which a short side of the first sheet is parallel to a sheet conveyance direction of the first sheet. The portrait orientation is an orientation in which a long side of the first sheet is parallel to the sheet conveyance direction. The change conveyance unit changes the conveyance orientation of the first sheet from the landscape orientation to the portrait orientation on a substantially horizontal region between the image forming apparatus and the feeding apparatus.
