A sheet post-processing device is mounted in an image forming apparatus that includes an image reading unit and an image forming unit. The image forming unit is located under the image reading unit with a space therebetween. The sheet post-processing device includes: a first tray that is located in the space and houses a sheet ejected from the image forming unit; a post-processing unit that is located in the space and performs post-processing on a sheet in the first tray; a transfer member that, after the post-processing is performed on a sheet in the first tray, transfers the sheet to a front side of the image forming apparatus; and a second tray that is located closer to the front side of the image forming apparatus than the first tray and houses a sheet transferred by the transfer member.
