ABSTRACT:
A clamshell type image forming apparatus, in which a process cartridge included in an upper structure is supported pivotably to a fixed position and a dismounting position against the upper structure, a developing unit included in a lower structure is supported thereon pivotably to a position just opposing to an image holding medium and a position spaced therefrom, and a plate spring which urges the developing unit toward a position spaced from the image holding medium is disposed on the lower structure side, and a plate spring which urges the developing unit toward a position just opposing to the image holding medium is disposed on the upper structure side, thereby inconveniences produced by providing the process cartridge on the upper structure are solved, and by reducing a collision between the developing unit and the image holding medium due to the open-and-close operation of the upper structure, it is possible to prevent a damage of the process cartridge including the image holding medium.
