摘要： In an image forming apparatus including plural exposure units each deflecting a light beam from a light source by means of an oscillation mirror in resonant oscillations and scanning the deflected light beam on a latent image carrier thereby forming a latent image on the latent image carrier, every one of the exposure units assuredly attains an adequate amplitude of the oscillation mirror for ensuring the formation of images of high quality. More specifically, a CPU 101 retrieves resonant frequencies of individual deflectors previously stored in a memory. The CPU 101 calculates an average value of these resonant frequencies and applies a drive command to mirror drivers 1022 of the exposure units 6Y, 6M, 6C, 6K such as to drive all the deflectors into oscillations at the average value. Alternatively, a resonant-frequency adjusting section 653 makes adjustment to match the resonant frequencies of the individual deflectors substantially with a drive frequency. This ensures that all the oscillation mirrors attain adequate amplitudes.

摘要： A scan-beam detection signal Hsync provided by horizontal synchronous sensors 60A, 60B is inputted to a drive signal controlling section 10Y as a drive period signal related to a drive period of a deflective mirror. The drive signal controlling section 10Y controls a drive signal Sd such as to establish a predetermined relationship between a phase of a reference signal Sr and a phase of the horizontal synchronous signal Hsync, whereby a deflector 65 is allowed to operate in synchronism with the reference signal Sr. Therefore, a latent-image forming position with respect to a sub-scan direction Y is adjusted by way of the phase adjustment between the reference signal Sr and the horizontal synchronous signal Hsync, so that a linear latent image is prevented from deviating with respect to the sub-scan direction Y.

摘要： Image data is inputted from a data processing means 123 into storage means 124 so that light emitting elements of one line 128a of a light-emitting element (yellow) line head 128 are activated to expose pixels on an image carrier according to an output signal form a shift resistor 124a. The image carrier is moved in the direction of arrow X in such a manner that the pixels reach a position corresponding to the light emitting elements in a next line 128b. At this point of time, the image data are transmitted to a shift resistor 124b and then outputted to the line 128b so as to expose the pixels again. The image data are transmitted among the shift resistors sequentially by moving the image carrier, thereby sequentially repeatedly expose the same pixels.
