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.

A paper feeding stand on which a recording apparatus such as a copying machine is mounted and which contains paper for recording and feeds the paper to the recording apparatus through intermediate rollers provided at the position opposing the paper entry of the recording apparatus according to the rotation of the intermediate rollers. When paper jam occurs between the intermediate rollers and the recording apparatus, the intermediate rollers are rotated in the reversal direction to return the paper to the intermediate roller section, and then the intermediate rollers are moved in the direction intersecting at right angles with the axial direction thereof to expose the intermediate rollers and the jammed paper to the outside so that the paper can be removed easily and surely without tearing.
