Abstract
In an apparatus for measuring a deposited toner amount of a toner patch formed on a toner carrier, an intersection between a light outgoing and incoming plane including an optical axis of the light emitting portion and light receiving portion of an optical sensor and a surface of the toner carrier is perpendicular to a direction of propagation thereof. The light outgoing and incoming plane is inclined at a mounting angle toward the direction of propagation of the toner carrier with respect to a plane including the intersection. A control unit calculates the deposited toner amount in accordance with one of a peak value and a bottom value of a sense voltage in a thickness determining region and calculates the deposited toner amount in accordance with the other of the peak value and the bottom value in an area determining region.
