Abstract: Provided are an image forming system and a method for detecting glossiness capable of accurately detecting glossiness in various media having different conditions.
The image forming system includes a sensor unit including a light source that irradiates a medium being conveyed with light and a gloss sensor that receives light emitted from the light source and specularly reflected on the medium and detects a diffusion distribution of light in the medium, and a detection condition setting unit that identifies a type of the medium being conveyed and sets a light amount of the light source and/or exposure time of the gloss sensor at the time of glossiness detection in accordance with the type of the medium. The image forming system further includes a glossiness detector that detects glossiness of the medium from a diffusion distribution of light detected by the gloss sensor under the detection condition set by the detection condition setting unit.

Abstract: A measuring device, includes a physical property value detector and a push contact member that pushes to bring a sheet material in contact with the physical property value detector; and further includes a first processor that stops conveyance of the sheet material, pushes to bring the sheet material in contact with the physical property value detector, and detects a physical property value of the sheet material; a second processor that, after having detected the physical property value, cancels the pushing by the push contact member, separates the sheet material from the physical property value detector, and starts conveyance of the sheet material; and a physical property value specifier that specifies the physical property value on a basis of physical property values of a plurality of positions within a surface of the sheet material detected by executing the first processing and the second processing repeatedly.

Abstract: A phase control device includes: at least one switching element connected to an AC power source, the switching element being capable of: turning on and off at specified timings; delivering AC power to a load upon turn-on and cutting it off upon turn-off; and keeping an on-time from the start to the end of turn-on and an off-time from the start to the end of turn-off, the on-time and off-time being variable; a timing setting portion that sets a turn-on and turn-off timing for turning on and off the switching element; a judgment portion that judges whether or not the turn-on and turn-off timing are on at a phase within a first or second phase range; and a processor that starts turning on and off the switching element at the turn-on and turn-off timing, the processor being capable of adjusting the on-time and off-time depending on the judgment result.

Abstract: An image forming apparatus that forms a color image by layering toner images of different colors includes: a photoreceptor on which an electrostatic latent image is formed through charging and exposure; an exposure unit performing exposure-scanning on the photoreceptor in accordance with image signal; an intensity determination unit determining exposure intensity according to image forming condition; and a timing determination unit determining a timing of inputting image signal for each scanning line, wherein the exposure unit has a delay duration differing depending on the exposure intensity and being from input of image signal of each pixel to be exposed to exposure of the pixel at the exposure intensity, and the timing determination unit obtains the delay duration corresponding to the exposure intensity, and determines the timing such that image signal of an initial pixel to be initially exposed is input the delay duration before the initial pixel is exposed.
