Abstract

A fullness detection device includes a waste toner collecting portion (43), a waste toner container (5) configured to store the collected waste toner, the waste toner container has translucency, a detecting portion (7) including a light emitting portion (71) and a light receiving portion (72) disposed to sandwich the waste toner container, the light receiving portion receiving the light from the light emitting portion, and a determining portion (6) configured to determine whether or not the waste toner container is full based on whether or not an output value of the light receiving portion is higher than a predetermined threshold value. The light emitting portion increases light intensity step by step and emits light at a level of smallest light intensity among light intensity levels at which it is determined that the waste toner container is not full.
