An image forming apparatus has an improved structure which avoids additional expenses associated with packing a developing unit and allows the developing unit to be stably stored. The image forming apparatus may include a body, a first developing unit accommodating portion and a second developing unit accommodating portion disposed at different positions in the body, and a developing unit which is allowed to be detachably accommodated in the first developing unit accommodating portion and the second developing unit accommodating portion. When accommodated in the first developing unit accommodating portion, the developing unit may be disposed such that it does not perform image formation. When accommodated in the second developing unit accommodating portion, the developing unit may be disposed to perform image formation.

An image forming apparatus has a structure which prevents contamination of charging units charging photoconductors. The image forming apparatus includes photoconductor units, charging units charging the photoconductor units, and a fan-motor unit changing the flow of air between the photoconductor units and the charging units to prevent substances of fine particles from flowing into the charging units.
