Abstract: A fixing device for performing a thermal fixing for fixing an unfixed image onto a recording sheet by passing the recording sheet through a fixing nip formed by a fixing rotator and a pressing member pressing the fixing rotator. The fixing device obtains a value indicating an amount of paper dust attached to the fixing rotator, and when the amount of paper dust indicated by the obtained value is equal to or larger than a permissible amount, performs a control so that a larger amount of heat is supplied to the recording sheet in the thermal fixing than when the amount of paper dust indicated by the obtained value is smaller than the permissible amount.

Abstract: An image forming apparatus includes an image forming section, a heat source, a fixing rotating body, a pressurizing rotating body, a feeding section for feeding a medium, a temperature adjusting section for controlling an amount of heat generated by the heat source, and a control section. The control section switches between a first mode in which the fixing rotating body and the pressurizing rotating body rotate at a first circumferential speed and the medium is fed to the image forming section at a first distance interval, and a second mode in which the fixing rotating body and the pressurizing rotating body rotate at a second circumferential speed higher than the first circumferential speed and the medium is fed to the image forming section at a second distance interval longer than the first distance interval.

Abstract: An example control signal generating circuit CTL for controlling the writing into pixels PIX instructs a data signal line drive circuit SD2, which is for driving pixels in a non-display area, to write a voltage VB or a voltage VW which are for non-displaying, not only in the first frame but also once in a predetermined number of frames. In other words, the pixels in the display area are refreshed at intervals longer than those in the case of refreshing the pixels in each frame.

Abstract: In case new and old toners may be mixed, a developing bias is set as follows. The time is first clocked. The number of times toner is replenished from a hopper into a buffer for a clocked period is counted. If a replenishment amount per clock time is a threshold value or higher, considering that new and old toners are mixed, the setting of the developing bias is changed. An electric field intensity between a developing roller and a photoconductor is set to cause normally-charged toner to fly in an image area but not to fly in a background area. No image fogging is therefore generated in the background area. Thus, an image forming apparatus and method capable of preventing low-charged toner and oppositely-charged toner generated by mixing of new and old toners from adhering to the background area of an electrostatic latent image on the photoconductor, thereby avoiding generation of image fogging.

Abstract: An instrument panel display system displays vehicle information, amenity information, and safety information as images. In this instrument panel display system, data (image data, image layout data, and image output control data) for displaying the images are generated in a shared manner by a vehicle system processor, an amenity system processor, and a safety system processor. On account of this, the stability of image display on an instrument panel of a vehicle or the like is improved and hence safety of driving is increased.

Abstract: An input signal INDATA inputted to a sender-side interface portion is encoded by an encoder, and a transmission signal generated by the encoding is transmitted to a receiver-side interface portion through two signal transmission lines. The input signal INDATA is encoded in such a manner that the logic level of the transmission signal transmitted through at least one of the two signal transmission lines is changed in any two consecutive elementary periods. The receiver-side interface portion is provided with a clock receiver, and a clock signal is generated based on the change of the transmission signals supplied from the two signal transmission lines.
