Abstract
An image forming apparatus includes an image forming device, a belt member, a reflection-type photosensor, and a reflection member. The belt member includes plural suction holes to attract a printing medium onto the belt member. The reflection member reflects light from the reflection-type photosensor through the suction holes. The reflection member is disposed inside the belt member. The reflection member has a reflection rate at which, when the reflection-type photosensor receives reflection light at positions of the suction holes with a transparent printing medium being not present on the belt member, a sensor output of the reflection-type photosensor is lower than a predetermined reference value, and when the reflection-type photosensor receives reflection light at the positions of the suction holes with the transparent printing medium being present on the belt member, a sensor output of the reflection-type photosensor is equal to or greater than the predetermined reference value.
