摘要： In a reflective optical sensor in an image forming apparatus, an output from each N number of light-receiving elements (N≧3), obtained when M number of light-emitting elements (M≧3) included in a light-emitting unit emit detecting light, is separated into an amount of specularly reflected light and an amount of diffusely reflected light. The toner density of a pattern, which is formed on a supporting member in the image forming apparatus, is calculated based on a sum of the amounts of specularly reflected light and a sum of the amounts of diffusely reflected light.
