Abstract
According to an aspect of the invention, an image writing apparatus includes an image writing unit, a moving unit, a positioning unit. The image writing unit faces an image carrier or a support member supporting a recording medium and writes an image on the image carrier or the recording medium. The moving unit moves the image writing unit between a first position and a second position apart from the first position. A positioning unit sets the image writing unit in the first position and includes a first restriction member, a second restriction member, a third restriction member, and a restriction releasing portion. The first restriction member restricts a first movement of the image writing unit along a first direction from the image carrier to the image writing unit or from the support member to the image writing unit.
