Abstract: An image forming apparatus includes a main assembly, a supporting member capable of supporting a plurality of developing rollers and a plurality of photosensitive drums, and a plurality of developing cartridges each having the developing roller. An urging member urges each developing cartridge to urge the developing roller toward the photosensitive drum, and a spacing member spaces the developing roller and the photosensitive drum from each other. The developing cartridges each include an upper surface facing upward when mounted to the supporting member and two recessed portions provided at the upper surface, each extending in a longitudinal direction of the developing roller, wherein the two recessed portions are disposed along an arrangement direction of the developing cartridges and constitute a gripping portion.

Abstract: A sheet stacking device including a stacking tray, an auxiliary tray, and pivot limiting means. The stacking tray is disposed to be pivotable relative to an apparatus main body. The stacking tray has a stacking surface on which sheets discharged from discharging means are stacked. The auxiliary tray is pivotable between a storage position at which the auxiliary tray is stored in the stacking tray and a pivot position to which the auxiliary tray pivots from the stacking tray. Pivot limiting means limits pivoting of the auxiliary tray from the pivot position when the stacking tray is caused to pivot
