    Abstract: 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.

    Abstract: In a device for controlling the amount of toner replenished to a developing device depending on the density of a reference image formed on a photoconductor, if the toner density of a developer in the developing device fluctuates extremely; there may occur toner scattering, formation of coarse or rough images, and carrier attachment. To overcome those problems, a photosensor is disposed to detect the toner density in the developing device, and when an output of the photosensor is outside of a predetermined range, a target value to be compared with the detected density of the reference image is modified.

    Abstract: An image forming apparatus includes a light emitting array composed of a plurality of light emitting elements that emits light fluxes. An imaging element array may be provided so as to perform imaging with the light fluxes on a prescribed plane. A three dimensional exposure intensity distribution of the light flux is obtained per each light emitting element. A prescribed attribute is obtained from each of the exposure intensity distributions. A plurality of comparison values for the entire exposure valid region may be obtained from different units which consist of two or more successive attributes. Prescribed light emitting quantities enabling all of the comparison values to fall within a prescribed range may be determined and set to respective light emitting elements.
