    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.

    摘要： A velocity detecting device includes an image-pattern acquiring unit that includes a laser light source and an area sensor that acquires a one-dimensional or a two-dimensional image. The image-pattern acquiring unit includes a lens between a moving member and the area sensor, irradiates a beam emitted from the laser light source to the moving member to make a scattering light of the moving member scattered from the moving member on the area sensor by using the lens, and acquires an image pattern at a predetermined time interval in association with movement of the moving member. A velocity calculating unit calculates the velocity of the moving member by computing the image pattern acquired by the image-pattern acquiring unit. The lens is a reduced optical system that projects a reduced object onto the area sensor.

    摘要： An image forming apparatus includes a fixing member, at least one reflective optical sensor, a heat shielding member, and a processor. The fixing member fixes an image on a recording medium moving in a first axis direction. At least one reflective optical sensor emits light toward the fixing member and receives light reflected by the fixing member. The heat shielding member is arranged between the fixing member and the at least one reflective optical sensor, has a light passing part through which light directed to the fixing member from the at least one reflective optical sensor and light reflected by the fixing member and directed to the at least one reflective optical sensor passes, and prevents heat transfer from the fixing member to the at least one reflective optical sensor. The processor is configured to obtain a surface state of the fixing member on the basis of an output signal from the at least one reflective optical sensor.
