An image forming apparatus includes an original scanning section, a sheet feeding section, an image forming section, a sheet receiving section and an indicator (LEDs). The image forming section is located between the original scanning section and the sheet feeding section and has a smaller cross-sectional area when cut by a horizontal plane than either of the original scanning section and the sheet feeding section such that a sheet receiving space into which each sheet of the printing medium is ejected is left between the original scanning section and the sheet feeding section. The sheet receiving section is located in the sheet receiving space for receiving the sheets of the printing medium ejected from the image forming section. The indicator notifies users that one or more sheets of the printing medium have been delivered to the sheet receiving section by emitting light.
