Image forming apparatus

An image forming apparatus comprising:

• an image forming apparatus main body;
• an image forming section that is arranged within the image forming apparatus main body, and that forms an image in a recording medium;
• a first driving source that is arranged within the image forming apparatus main body;
• a discharging member that is rotated in a normal direction by the first driving source, and that discharges the recording medium on which the image is formed by the image forming section;
• a driving source assembly body that includes a second driving source for normally and reversely rotating the discharging member;
• and
• a both-face printing assembly body that inverts the recording medium pulled-back by reversely rotating the discharging member, and that returns the recording medium to the image forming section,
• the driving source assembly body and the both-face printing assembly body being separately freely attached and detached with respect to the image forming apparatus main body.
