Abstract: A sheet feeding apparatus and an image forming apparatus which can reliably feed even sheets having a non-uniform thickness to prevent excessive stacking.An auxiliary tray 1 is swingably provided on the upper surface of a tray 2 which is provided in a cassette body 3a to be lifted and lowered and stacks sheets thereon. When the sheets are stacked, a swing regulating portion 12 regulates the swing of the auxiliary tray 1 when the tray 2 is in a sheet stacking position and releases the regulation of the swing of the auxiliary tray 1 when the tray 2 is lifted.

Abstract: An image forming apparatus capable of selectively discharging a sheet having an image formed with toner on one surface thereof and a sheet having images formed with toner on both surfaces thereof includes a fixing unit configured to fix a toner image on a sheet, a sheet stacking portion configured to stack sheets each having the toner image fixed thereon, and a control portion configured to control a maximum sheet stacking amount of sheets stacked in the sheet stacking portion. The control portion controls the maximum sheet stacking amount set when sheets, at least one of which has the toner images formed on both surfaces thereof, are stacked to be smaller than the maximum sheet stacking amount set when sheets each having the toner image formed on one surface thereof are stacked.

Abstract translation: 一种图像形成装置，其能够选择性地排出具有在其一个表面上形成有调色剂的图像的片材和具有在其两个表面上形成有调色剂的图像的片材，其包括定影单元，其被配置为将调色剂图像定影在片材上，片材堆叠部分 被配置为堆叠其上固定有调色剂图像的片材;以及控制部分，其被配置为控制堆叠在片材堆叠部分中的片材的最大片材堆积量。 控制部分控制当片材（其中至少一个具有形成在其两个表面上的调色剂图像）堆叠时的最大片材堆积量小于当其上形成有调色剂图像的片材时设定的最大片材堆积量 其表面堆叠。
