    Abstract: An image forming apparatus that can reduce the number of signal lines that can respond to interrupt processing by conducting I/O control that can acquire irregularly generated sensor detection signals. Identification control means of the image forming apparatus uses the data line in the period other than when conducting identification control of the detection means or the drive means to acquire the data of the specified detection means as valid data. Delay of the detection response time to irregularly generated signals can be minimized by using the data line other than when conducting identification control of the detection means or the drive means to acquire irregularly generated detection signals.

    Abstract: An image forming apparatus capable of decreasing the image unevenness of a superimposed image at the time of forming starting (head) lines of the images in respective colors with different beams in order to decrease a shift of a superimposed image. Let a position, where an image in a first color is formed with a beam A as a leading beam, be (a). Let a starting position of formation of an image in a second color be (b), and one dot (line) of shift arises in the superimposed image. In order to decrease the shift of the superimposed image, image formation is performed with selecting a beam B as a beam which writes a head of the image (c). When image formation is performed for color shift reduction with changing a leading beam for each color image, tonality correction is performed to each beam for subsequent images so as to decrease image unevenness due to the difference between shapes and exposure power of respective beams.

    Abstract: An image clock signal generating system generates an image clock signal which is used to enable and disable a scan of an optical scanner, and comprises a phase locked loop (PLL) circuit for generating an image clock signal in response to a reference pulse signal which comprises a plurality of pulses during a time corresponding to a scan range of the optical scanner and no pulses during a time corresponding to a no-scan range of the optical scanner. The PLL circuit includes a phase comparator which receives the reference pulse signal and a feedback signal and outputs a phase error signal dependent on a phase error between the two signals, a voltage controlled oscillator (VCO) for outputting an image clock signal, and an initial phase matching circuit for outputting the feedback signal in response to the image clock signal output from the VCO. The initial phase matching circuit outputs the feedback signal with an initial phase which makes the phase error between the reference pulse signal and the feedback signal approximately the same as a predetermined phase error detected in the phase comparator when the PLL circuit is in a locked state.

    Abstract: A semiconductor laser control apparatus for controlling an optical output of a semiconductor laser comprises a correcting part supplied with a modulation signal which determines ON and OFF states of the semiconductor laser for outputting a processed modulation signal, and a driving circuit supplied with the processed modulation signal from the correcting part for supplying a driving signal to the semiconductor laser. The correcting part includes a differentiating circuit responsive to the processed modulation signal for supplying a correction signal having a predetermined time constant to the driving circuit when the semiconductor laser is ON so as to maintain the optical output of the semiconductor laser constant, and a pulse width correcting circuit for correcting a pulse width of the modulation signal to obtain the processed modulation signal. The processed modulation signal is supplied to the driving circuit so that the semiconductor laser is ON and operates until a time which is delayed by a predetermined delay time from an operation end time determined by the modulation signal.
