An image forming device, which is configured to form an image on a sheet, includes a main body casing, a catch tray provided on the main body casing to be loaded with the sheet discharged in a first direction with the image formed thereon, and a cover configured to cover a downstream-side face of the main body casing in the first direction in an openable and closable manner. The catch tray is disposed such that a downstream-side end thereof in the first direction faces an upstream-side end of the cover in the first direction. The downstream-side end of the catch tray and the upstream-side end of the cover are configured to mutually overlap when viewed in a second direction perpendicular to the first direction and a vertical direction.
