Abstract
Provided are a first detecting unit having a singular first light-receiving element disposed to face a direction of normal reflection of light, the light having been emitted from a first light-emitting element toward a first detection image formed on the rotary member and reflected thereat, and a second detecting unit having a singular second light-receiving element disposed to face a direction different from a direction of normal reflection of light, the light having been emitted from a second light-emitting element toward a second detection image formed on the rotary member and reflected thereat. A value relating to toner density is obtained based on a first detection result detected by the first detecting unit and a second detection result detected by the second detecting unit.
