摘要： An image forming apparatus comprises a pickup roller for picking up paper from a paper supply part and supplying the paper directly to a transfer nip (that is, the contact formed between a photoconductive drum and a transferring roller), a laser scanning unit for scanning a certain light onto the photoconductive drum, a paper sensor for detecting the top end of the paper being picked up and supplied by the pickup roller, a paper entry sensor for detecting the entry of the paper into the transfer nip, and a controller for updating a scanning point of the laser scanning unit based on the time from the detection of the top end of the paper by the paper sensor to the time the paper entry sensor detects entry of the top end of the paper into the transfer nip. Using this apparatus, an actual time for transferring the paper from the point of detecting the top end of the paper to the point of entrance of the paper into the transfer nip, is calculated, a shift amount with respect to a top margin stored to a controller is calculated based on the calculated information, the top margin value is updated by compensating the shift amount, and upon the error compensation, a light is scanned onto a following sheet of the paper by applying the updated top margin value, thereby processing an image. Accordingly, the top margin can be constantly maintained.

摘要： A developer cartridge includes a cartridge body comprising a developer discharge port, a remaining developer detecting unit arranged in the proximity to the developer discharge port, and an agitating unit rotatably arranged inside the cartridge body to convey the developer accommodated in the cartridge body toward the developer discharge port. Since the optical sensor provided in the image forming apparatus body is capable of physically measuring an exact amount of remaining sensor of the developer cartridge, a printing error due to erroneous determination of the remaining developer amount can be prevented.

摘要： An image forming apparatus feeds a paper picked up by a pickup roller directly to a photoconductive drum and controls a linear velocity of the pickup roller so that it is slower than that of the photoconductive drum. The different linear velocities of the pickup roller and the photoconductive drum produces different velocities at the transfer nip (the area of contact between the photoconductive drum and a transferring roller) and the point where paper is picked up by the pickup roller. To compensate for the different velocities, the pickup roller can be rotated faster than the photoconductive drum for an angle that corresponds to the velocity difference. Additionally, when a velocity difference occurs between two rollers for feeding the paper, one of the rollers can be further rotated to compensate for the velocity difference.
摘要翻译：图像形成装置将由拾取辊拾取的纸张直接馈送到感光鼓并且控制拾取辊的线速度使其比感光鼓的线速度慢。拾取辊和感光鼓的不同线性速度在转印辊隙（感光鼓和转印辊之间的接触区域）以及由拾取辊拾取纸张的位置产生不同的速度。为了补偿不同的速度，拾取辊可以比对应于速度差的角度比感光鼓旋转得更快。此外，当在用于馈送纸张的两个辊之间发生速度差时，可以进一步旋转一个辊以补偿速度差。
