摘要： An image forming method which generates a video signal corresponding to an image forming command based on a video clock signal, modulates a light beam according to the video signal, and scans the modulated light beam along a main scanning direction by means of an oscillation mirror which resonates based on a drive signal, so as to form a latent image in an effective image region of a latent image carrier, the method includes: synchronizing the drive signal with the video clock signal to synchronize a detection signal with the video clock signal, the detection signal being output from a detector which detect the light beam scanned in the main scanning direction in a region away from an effective scan region which corresponds to the effective image region; controlling a resonant frequency of the oscillation mirror based on the detection signal so that the resonant frequency of the oscillation mirror almost coincides with the frequency of the drive signal; and adjusting a position, at which the latent image is written over the latent image carrier, is adjusted by adjusting output timing of the video signal based on the detection signal from the detector.

摘要： The invention provides a developing device employing a liquid developer which is capable of effectively cleaning a development roller or the like having an elastic outer layer. The developing device of the invention is provided with an elastic roller such as a development roller for developing a latent image formed on an image carrier. In image forming process, toner particles uniformly dispersed in carrier are agglutinated to the elastic roller side by means of compaction. A cleaning blade is provided for cleaning the agglutinated toner particles. Assuming that an angle of a contact face of the cleaning blade relative to a perpendicular line perpendicular to a generating line of the elastic roller at a contact point where the tip end of the cleaning blade is pressed against and in contact with the elastic roller is θ and an angle of a rising contour of a deformed portion of the elastic outer layer which is deformed by the pressure of the cleaning blade against the elastic roller relative to the perpendicular line is a, a relation a>θ is established.
