  • Patent number: 9250596
    Abstract: An image forming apparatus includes a vibration adjustment unit which adjusts a natural frequency of an optical system, a measuring unit which measures vibrational information indicating change in vibration, and a controller which individually drives each unit. The measuring unit measures the vibrational information after the natural frequency is adjusted to a drive frequency of each unit at an initial state. The controller stores this vibrational information as initial vibrational information. The measuring unit measures the vibrational information after the natural frequency is adjusted to a drive frequency of a unit to be checked. The controller compares this vibrational information with the initial vibrational information measured after adjustment of the natural frequency to the drive frequency of the unit to be checked. The controller determines abnormality in the unit to be checked according to the comparison.

  • Patent number: 9056510
    Abstract: An image forming apparatus A includes: a light irradiation device 3 which irradiates laser light; an image carrying body 1 which is exposed to the laser light to form a latent image on the exposed portion; and an abutting member 31 which is fastened to the light irradiation device in abutting contact with a stationary member F for defining a reference position. The abutting member 31 changes in volume due to temperature fluctuation, and the light irradiation device 3 moves with respect to the stationary member F, in an opposite direction to a focal point shift which has taken place along an irradiation direction of the laser light due to the temperature fluctuation.

  • Patent number: 8730292
    Abstract: A scanning optical device that scans a photoreceptor with laser light includes a light source, a light outputting section, and a projection. The laser light from the light source is output through the light outputting section so that the photoreceptor is irradiated with the laser light. The projection projects through a partition wall toward the photoreceptor. The light outputting section is disposed in a position separated from the photoreceptor by the partition wall. The projection contains a polygon motor that rotates a polygon mirror to reflect the laser light.
