Abstract
An image forming apparatus includes a pair of optical sensing devices for monochrome image forming and full-color image forming which are disposed at the rear of the image forming apparatus and a pair of generally L-shaped light shielding members for monochrome image forming and full-color image forming which are mounted swingably on a rear side of an image transfer unit with one end of each light shielding member attached to one of two sliding members. When each of the sliding members moves back and forth, the light shielding member for monochrome image forming or full-color image forming, whichever applicable, swings and the relevant optical sensing device detects the other end of the light shielding member.
