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 vide 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： An image forming apparatus adapted for a smooth mounting/dismounting of a process unit and for the reduction of wasteful power consumption is provided.Unless a new image signal is applied after completion of an image forming operation, the apparatus starts a clocking operation by an internal timer (Step S101). If the apparatus is left standstill for a predetermined length of time (Step S102), a sleep process (Step S103) is executed to shift the apparatus to a power save mode to consume less power. When an outside cover is opened (Step S105), on the other hand, the apparatus is shifted to a replacement operation mode (Step S106) in which only the rotation of a development rotary is permitted. However, if the apparatus is left with the outside cover opened (Step S108), the sleep process is executed.

摘要： As a scanning light beam which is scanning and traveling away from an effective image region moves passed the location of a sensor, a horizontal synchronizing signal Hsync is obtained as a first detection signal. A deflection mirror surface turns around, thereby reversing the direction in which the scanning light beam scans. This scanning light beam therefore scans an effective image region IR, and a latent image forming operation using this scanning light beam is controlled based on the horizontal synchronizing signal Hsync. Hence, there is a relatively long period of time (T4+T5) since the horizontal synchronizing signal Hsync is obtained until formation of a latent image starts in accordance with the signal Hsync. This secures sufficient time for control of the latent image forming operation based on the horizontal synchronizing signal Hsync, and hence, realizes the latent image forming operation as desired during the time T6.
摘要翻译：当扫描并远离有效图像区域移动的扫描光束通过传感器的位置时，获得水平同步信号Hsync作为第一检测信号。偏转镜面转过来，从而反转扫描光束扫描的方向。因此，该扫描光束扫描有效图像区域IR，并且基于水平同步信号Hsync来控制使用该扫描光束的潜像形成操作。因此，由于根据信号Hsync，直到开始形成潜像，才获得水平同步信号Hsync，所以存在相当长的时间段（T 4 + T 5）。由此，能够根据水平同步信号Hsync确保足够的时间进行潜像形成操作的控制，从而在时刻T 6期间根据需要实现潜像形成动作。

摘要： A mirror driver drives deflection mirror surfaces into a pivoting action at a frequency belonging to a first drive frequency band in which the high-frequency side of a first resonance frequency band partially overlaps the low-frequency side of a second resonance frequency band, so that the deflection mirror surfaces deflect a light beam. Hence, the deflection angles of light beams change, while canceling out each other the changes of the deflection angles of the light beams deflected by the deflection mirror surfaces owing to changes of resonance characteristics. Because of this, even when the resonance characteristics change, it is possible to stabilize the deflection angle of the light beam deflected by the first deflection mirror surface and further deflected by the second deflection mirror surface.
摘要翻译：反射镜驱动器将偏转镜面驱动成属于第一驱动频带的频率的转动动作，其中第一共振频带的高频侧部分地与第二共振频带的低频侧重叠，使得偏转镜面偏转光束。因此，由于共振特性的变化，光束的偏转角变化，同时抵消由偏转镜面偏转的光束的偏转角的变化。因此，即使在谐振特性变化的情况下，也可以使由第一偏转镜面偏转的光束的偏转角稳定，并进一步被第二偏转镜面偏转。

摘要： An image forming apparatus includes development cartridges which develop an electrostatic latent image with toner, a rotary unit provided with the developing cartridges, an intermediate transfer belt which receives the toner image, and a controller. A length of the intermediate transfer belt is set such that a length of the image forming region is corresponded to a length of a set recording medium having a predetermined size and a length of the non-image forming region is corresponded to a distance between a rear end of the preceding one of the set recording mediums and the front end of the subsequent one. A rotational movement period of the intermediate transfer belt corresponding to the length of the non-image forming region is equal to or greater than a time required for switching the developing cartridges. The controller performs an switching operation of the developing cartridges in accordance with a size of a recording medium.
