A moving body reciprocation mechanism has a rotation shaft and a moving body that engages with a spiral ridge part of the rotation shaft and reciprocates along an axial direction. The state of the moving body changes among: a first state in which the moving body moves in a first movement direction; a second state in which the moving body releases the engagement; and a third state in which the moving body reengages with the spiral ridge part and moves in a second movement direction. The rotation shaft has a planar part and a cylindrical protrusion part. A cylinder part of the moving body has: a first end part that fits onto the cylindrical protrusion part in the second state; and a second end part that radially faces an outer circumferential surface of the spiral ridge part in the second state.

An image forming apparatus includes an apparatus main body and a unit. The unit is detachably attached to the apparatus main body along one direction. The apparatus main body includes a main body side board and a main body side connector. The main body side connector is mounted on the main body side board. The unit includes a unit side board, a unit side connector, a supporting member and a biasing member. The unit side connector is mounted on the unit side board and fitted to the main body side connector from a first side in the one direction as the unit is attached to the apparatus main body. The supporting member supports the unit side board so as to be movable along the one direction. The biasing member biases the unit side board to a second side in the one direction.
