摘要： A toner-concentration controller includes a controller configured to control a toner supply amount in accordance with a detection result of a toner-concentration of two-component toner, and a sensor unit configured to detect the toner-concentration of two-component toner. The sensor unit includes a correction mechanism to correct an output signal of the sensor unit by changing an external-input voltage, based on relationship data between an output voltage change of the sensor unit and a toner-concentration of unused developer, to control the toner supply amount when the toner-concentration of the two-component toner deviates a predetermined amount from the toner-concentration of the unused developer. The sensor unit is configured to detect the toner-concentration of the unused developer from unused two-component toner based on a change in the external-input voltage.

摘要： A developing unit supplies toner from a developing roller to an electrostatic latent image formed on an image carrier, and creates a visual image. A forced consumption unit causes, when a proportion of number of pixels used for forming the electrostatic latent image for a maximum image effective-width is equal to or less than a predetermined value, a forced consumption of toner by an amount corresponding to a difference between a toner amount corresponding to the number of pixels and a predetermined toner consumption amount. The forced consumption unit adds toner of an amount used in the forced consumption to an amount of toner to be supplied in a next imaging process.

The method includes the steps of computing a normalization value as a relative output ratio of the regular reflection output to a background regular reflection component from the surface extracted from the regular reflection light, in which the regular reflection output is obtained by detecting a plurality of gradation toner patterns with a sensor configured to simultaneously detect regular reflection light and diffuse reflection light; obtaining a diffuse reflection output conversion factor by either (1) subtracting the normalization value multiplied by the diffuse reflection output voltage generated by the surface from the diffuse reflection output voltage, or (2) subtracting the normalization value multiplied by a diffuse reflection output voltage increment, which is computed as the difference between the diffuse reflection output voltage and another diffuse reflection output voltage obtained when a light emitting device is turned off, from the diffuse reflection output voltage increment; and subjecting the relation between the diffuse reflection output conversion factor and the amount of adhesion to a polynomial approximation.
