摘要： In an image forming apparatus, the number of components and a size of the apparatus is reduced by realizing both functions for detecting a toner patch image to perform image quality adjustment and for performing precise color adjustment depending on a sheet color with one color sensor. The color sensor is disposed in a vicinity of a transport belt, a reference toner image is formed on the transport belt at a predetermined timing. A color of the reference toner image formed on the belt is detected by the color sensor to adjust development conditions. Further, the sheet is transported in a state where the transport belt is separated from a photoreceptor drum, and the sheet color is detected by the color sensor, and thereafter the transport belt touches the photoreceptor drum to transport the sheet to a transfer portion.

摘要： There are provided a fixing device and an image forming apparatus capable of reducing a sensing error of a surface temperature of a heating roller. The fixing device includes a temperature sensor for sensing the surface temperature of the heating roller, and a temperature calculation circuit. The temperature calculation circuit includes a noise removal prevention circuit. The temperature sensor includes an infrared ray sensing thermistor and a compensation thermistor, and the noise removal prevention circuit prevents removal of a part of an AC component (such as a high frequency component in a noise) included in a difference between outputs (difference output) of the infrared ray sensing thermistor and the compensation thermistor. Thus, the AC component is prevented from being offset when the difference outputs are averaged, thus reducing the sensing error of the surface temperature of the heating roller based on the average value of the difference outputs.

摘要： A control circuit for outputting a signal for controlling an amount of light emitted from a plurality of light emitting elements. The control circuit includes a controller or CPU, and a D/A converter outputting a signal for setting a voltage in multiple gradation in accordance with a lighting state of the light emitting element. An amplifying circuit amplifies an output of the D/A converter and outputs an amplified output as a control signal. A reference voltage generating circuit generates a reference voltage and a comparator compares the control signal with the reference voltage. The controller varies an output of the D/A converter based on the result of comparison by the comparator, to adjust the output of the D/A converter so that the control signal is equivalent to the reference voltage. Accordingly each voltage is reset in the multiple gradation to allow the light emitting element to appropriately emit light based on the adjusted output. As a result, a plurality of light emitting elements can be controlled stably without using a high precision circuit element.
