摘要： A control portion obtains a first difference in a movement amount between paper passing period and paper non-passage period of a transfer belt, and determines whether or not a first absolute value thereof is a first threshold value or more. In a case where the first absolute value is the first threshold value or more, a transfer belt unit positional adjustment motor is driven to adjust a first angle with respect to a first direction of a transfer belt unit with respect to a photoreceptor drum. In a case where the first absolute value is less than the first threshold value, a second absolute value of a second difference between a movement amount and a designed value set in advance of the transfer belt is obtained, and whether or not the second absolute value is a second threshold value or more is determined. When the second absolute value is less than the second threshold value, the processing is finished, and when the second absolute value is the second threshold value or more, a second angle with respect to a second direction orthogonal to the first direction of the driving roller with respect to the photoreceptor drum is adjusted so as to be less than the second threshold value by a driving roller positional adjustment motor.

摘要： A belt carrying device includes supporting rollers, an endless belt supported by the supporting rollers, and guiding members provided on the endless belt. The endless belt is rotated by rotation of the supporting rollers. An outer peripheral surface of the endless belt is in contact with a cleaning member. The guiding members are provided on those projecting areas of the endless belt, which project in an axial direction of the supporting rollers from both end surfaces of the supporting roller. A guiding member suppresses meandering of the endless belt by coming into contact with an end surface of the supporting roller. Formed on the end, surfaces of at least one of the supporting rollers are projecting sections and groove sections, which are rotated around a rotation axis of the at least one of the supporting rollers in response to rotation of the at least one of the supporting rollers.

摘要： For an image display apparatus, cost reduction is enabled to prevent display errors while ensuring operational margin to prevent display errors even when the delay time of gate line driving signals is large. A source driver of a liquid-crystal display apparatus includes a data latch circuit for supplying display data to a decode circuit. A gate line inactivation transition detecting circuit detects inactivation of each of a plurality of gate lines and activates a detect signal for a certain period with that timing. The data latch circuit updates the held display data in response to activation of the detect signal.

摘要： In an image forming method, an electrostatic latent image formed on a surface of a photoreceptor is developed into a developer image with a developer, and a printing paper transported on a transfer belt is brought into contact with the surface of the photoreceptor so as to transfer the developer image onto the printing paper. The printing paper is transported in a proper transport direction, in which a projection generated in one direction on the printing paper as a result of cutting the printing paper in a printing paper manufacturing process does not face a surface of the transfer belt at a leading edge of the printing paper being transported on the transfer belt. In this way, even in the presence of the projection generated when the printing paper is cut, the printing paper naturally strips off from the surface of the photoreceptor, thereby preventing toner contamination caused by a striping claw in contact with the leading edge of the printing paper.

摘要： In an image forming apparatus, an electrostatic latent image formed on a surface of a photoreceptor is developed into a toner image. A printing paper transported on a transport belt is brought into contact with the surface of the photoreceptor and an electric field is applied to the printing paper from a rear surface of the transport belt by a transfer roller to transfer the toner image onto the printing paper. The transfer roller applies different levels of electric field to the printing paper, so that a predetermined transfer electric field is applied to a region other than a leading edge of the printing paper being transported. An electric field weaker than the predetermined transfer electric field is applied to the leading edge. Even in the presence of a projection generated when the printing paper is cut, the printing paper naturally strips off from the surface of the photoreceptor.

摘要： A level shifter and a charge pump circuit are added, among cascade-connected unit frequency dividing circuits forming a frequency dividing circuit, to the unit frequency dividing circuit in the first stage. The charge pump circuit boosts an input voltage based on a dot clock signal, and supplies the booster voltage to the unit frequency dividing circuit in the first stage. The unit frequency dividing circuit in the first stage, which is driven by the booster voltage, attains an improved current driving capability. The improved current driving capability of the unit frequency dividing circuit in the first stage to which the dot clock signal of high frequency is input leads to a widened operating margin of the frequency dividing circuit.

摘要： A sheet conveying device that facilitates solution of a jam of a sheet and which is capable of inhibiting shortening of life due to a jam is provided. A sheet having a bent leading end that is very likely to jam is positively made to jam at a blocking portion formed on an upstream side of an image forming station in a sheet conveying direction thereof. Consequently, it is possible to more easily perform an operation of solving a jam than in a case where a jam of the sheet occurs in the image forming station. Moreover, it is possible to prevent deterioration of the image forming station due to a jam, and inhibit shortening of the life of the image forming station resulting from a jam.
