Abstract: An image forming device includes: a sheet feeder that feeds a sheet; a controller that: discriminates a sheet type of the sheet, and receives a user input to specify a sheet type; and an image forming device that has two setting modes including an automatic discrimination mode in which an image is formed based on the discriminated sheet type and a user specified mode in which an image is formed based on the sheet type specified by the user input. The controller automatically switches one of the two setting modes to the other based on a defined condition.

Abstract: An image reading apparatus includes: three or more light sources configured to each emit light; a light receiving unit including a common light receiving surface configured to detect each light emitted; and an image generation unit configured to cause the three or more light sources to be switched over in a predetermined order and emit the corresponding light, and generate an image read from a document, wherein at least one of the three or more light sources includes a white light source and an optical filter, and the optical filter is configured such that a half-value width of a wavelength with respect to a maximum intensity of a spectral characteristic of the emitted light after transmission is wider than a half-value width of a wavelength with respect to a maximum intensity of the spectral characteristic of the light emitted from at least one of the other light sources.

Abstract: An image forming apparatus includes an image forming section to form a toner image and transfer the toner image to a recording medium and a fixing section to heat the recording medium transferred with the toner image and further an image analyzing section to extract a density value or a size value of an imaging object included in an image, and a temperature determining section to determine a minimum fixing temperature based on the density value or size value of the imaging object included in a page image. The temperature determining section determines the minimum fixing temperature to be lower when a highest one of the density values is lower than when the highest value is higher or determines the minimum fixing temperature to be lower when a largest one of the size values is smaller than when the largest size value is larger.

Abstract: A heater control device that performs phase control of AC power and supplies phase-controlled power to a heater, the heater control device including: a control unit configured to, in the phase control, gradually increase an on-duty ratio until a target power amount is supplied to the heater; and a judgment unit configured to judge whether or not the on-duty ratio is within a predetermined range of on-duty ratios including a 50% on-duty ratio. The control unit (i) increases the on-duty ratio by a first amount while the on-duty ratio is within the predetermined range, and (ii) increases the on-duty ratio by a second amount while the on-duty ratio is not within the predetermined range. The first amount is greater than the second amount.
