Abstract: An image forming apparatus includes a main casing; a photosensitive member; a process cartridge that can be installed or removed with respect to the main casing along a removal path; a pick-up roller located above a sheet accommodating portion; and a feed path along which a sheet can be conveyed from the sheet accommodating portion to a discharge port. At least a part of the feed path is substantially parallel to the removal path and located between the sheet accommodating portion and the process cartridge when the process cartridge is installed in the main casing; and an image forming position where an image is transferred from the photosensitive member to the sheet is located along the feed path at a position lower than an upper surface of the pick-up roller in a verticle direction.

Abstract: A fixing unit is disposed at a position closer to a rear side wall than to a front side wall of a casing. A top wall is formed with a depressed portion depressed toward inside the casing. The depressed portion serves as a sheet discharge tray for receiving a recording medium that has passed through the fixing unit. The sheet discharge tray includes a tray member detachably disposed at the top wall. The rear side wall is formed with an opening through which the fixing unit is removed. When the tray member is disposed at the top wall, the tray member is positioned above and adjacent to the fixing unit and overlaps the fixing unit when viewed through the opening, thereby preventing the fixing unit from being removed from the casing. The fixing unit is removable through the opening when the tray member is detached from the top wall.

Abstract translation: 固定单元设置在比壳体的前侧壁更靠近后侧壁的位置。 顶壁形成有朝向壳体内侧凹陷的凹部。 凹部用作用于接收通过定影单元的记录介质的片材排出托盘。 片材排出托盘包括可拆卸地设置在顶壁处的托盘构件。 后侧壁形成有开口，固定单元通过该开口被移除。 当托盘构件设置在顶壁时，托盘构件定位在定影单元的上方并与其相邻，并且在通过开口观察时与定影单元重叠，从而防止定影单元从壳体移除。 当托盘构件与顶壁分离时，固定单元可通过开口移除。

Abstract: A curl-correcting device includes a first curl-correcting section and a second curl-correcting section. The first curl-correcting section is disposed on a conveying path along which a recording medium is conveyed in a conveying direction. The first curl-correcting section corrects curl in a recording medium having a first thickness. The second curl-correcting section is disposed on the conveying path either upstream or downstream of the first curl-correcting section in the conveying direction. The second curl-correcting section corrects curl in a recording medium having a second thickness greater than the first thickness.
