摘要： A sheet discharge apparatus includes a main tray, a discharge unit, and an expansion tray. The main tray is pivotable between a closed position and open position relative to a sheet discharge apparatus main body. The discharge unit discharges the sheet onto the main tray in the closed position. The expansion tray expands a main tray stacking area and is movable between a storage position where the expansion tray is stored in the main tray and an expansion position where the expansion tray is slid from the storage position in a sheet discharge direction and expands the stacking area. At the expansion position, the expansion tray is pivotable independently of the main tray. A direction in which the expansion tray is pivoted upward is the same as a direction in which the main tray is pivoted from the closed to the opened position.

摘要： The image forming apparatus includes a sheet storing unit insertably and pullably attached to the frame unit, an image forming unit, and a frame unit. The frame unit includes two frame members parallel to each other with a predetermined distance therebetween and are connected and fixed to each other. The two frame members respectively include engaged portions. The sheet storing unit includes engaging portions respectively engageable with the engaged portions in a state where the sheet storing unit is inserted in the frame unit. In a state where the engaging portions respectively engage with the engaged portions, the engaging portions that respectively engage with the engaged portions and a portion between the two engaging portions of the sheet storing unit serve as strengthening members to regulate deformation of the two frame members by at least a predetermined amount.
