摘要

An image forming apparatus of the type having a sheet discharging section provided in an upper portion of a body of the apparatus, a stacking section for stacking a sheet driven out via the sheet discharging section, and a casing accommodating a sheet conveying mechanism. An inclined surface is formed on top of the stacking section and inclines obliquely downward toward the sheet discharge section. A guide on the bottom of the casing is used for sliding against the inclined surface when the casing is mounted to the body of the apparatus.
