Abstract: An image forming apparatus includes: a storage container which horizontally stores a waste toner; a full detection sensor which detects whether the waste toner reaches a full position; a near detection sensor which detects whether the waste toner reaches a near position; and a conveyance portion which is provided inside the storage container, includes an axial rod, and rotates about the axial rod, wherein the conveyance portion includes: a first spiral protrusion which conveys the waste toner to the near position; a second spiral protrusion which conveys the waste toner from the near position to the full position; and a third range which is provided between the first spiral protrusion and the second spiral protrusion and through which the waste toner passes at a speed lower than the conveyance speed of the first spiral protrusion and the second spiral protrusion.

Abstract: A fixing device includes a first and a second rollers which form a fixing nip portion, a separating member for sheets, a supporting mechanism and a contact portion. The separating member is displaced between a first posture in which the tip of the separating member is close to the circumferential surface of the first roller and a second posture in which the tip is distant from that. The contact portion forms a gap between the tip of the separating member and the circumferential surface of the first roller. The supporting mechanism includes a pair of supporting members arranged near the opposite ends of the first roller, pivot members extending from the separating members and serving as a pivot of rotation of the separating member, and long holes which are provided at the opposite ends of the separating member and into which the pivot members are inserted.
