  • Publication number: 20240168163
    Abstract: An optical sensor includes a light-projecting element that projects detection light; an optical axis adjustment element that adjusts an optical axis of the detection light; a light-receiving element that receives the detection light reflected at a target object and outputs a detection signal; a reception unit that receives a specified condition relating to a detection result obtained via preliminary detection of a target object; and a control unit that sets, as an inspection direction, a direction of the detection light in which, of detection results based on the detection signal obtained by scanning a preliminary target placed in advance with the detection light by driving the optical axis adjustment element, a detection result corresponding to the specified condition is obtained, and drives the optical axis adjustment element to cause the detection light to be projected, in the inspection direction set, for an inspection target placed instead of the preliminary target.

  • Patent number: 11971675
    Abstract: An image forming apparatus includes image bearers, motors, a reference position detector, and processing circuitry. The circuitry senses a density of a toner image on each bearer; forms an image pattern and senses, based on a detection result of the detector and a sensing result of the density, density unevenness in a rotation cycle and a phase of the density unevenness with respect to a rotational position reference of each bearer; calculates a target phase based on the phase sensed; calculates a relative phase difference based on a rotational position and the target phase of each bearer; selects, as a reference image bearer, an image bearer having a minimum phase correction value, based on a calculation result of the difference; and controls the rotational position of each of the other image bearers with respect to the reference image bearer to the phase correction value, with the motors being driven.
