摘要： A method for forming an image in an electrophotographic printer. The method includes the steps of rotating a developing roller at the same linear velocity as that of a photosensitive medium in a state where the developing roller is separated from the photosensitive medium, moving a developer so that the developing roller is in contact with the photosensitive medium, and changing the linear velocity of the developing roller to be faster than that of the photosensitive medium after contact and proceeding with the developing process, rotating the developing roller at the same linear velocity as that of the photosensitive medium after completing the developing process, and moving the developer so that the developing roller is separated from the photosensitive medium. The linear velocity of the developing roller is equalized with that of the photosensitive drum whenever the developing roller is attached to or detached from the photosensitive medium, the toner supply to the photosensitive medium during development is sufficient, and shock caused by the attaching and detaching operation is alleviated, thereby greatly reducing the possibility of defective images.
摘要翻译：一种用于在电子照相打印机中形成图像的方法。该方法包括以下步骤：在显影辊与感光介质分离的状态下以与感光介质相同的线速度旋转显影辊，移动显影剂使得显影辊与感光介质接触，并且在接触之后将显影辊的线速度改变为比感光介质的线速度快，并且继续显影过程，在完成显影过程之后以与感光介质相同的线速度旋转显影辊，以及移动显影剂使得显影辊与感光介质分离。显影辊的线速度与感光鼓的线速度均匀，只要显影辊被附着到感光介质上或从感光介质上分离，在显影过程中向感光介质供应的调色剂就足够了，并且由附着和拆卸操作引起的冲击被减轻，从而大大降低图像缺陷的可能性。

摘要： A developing apparatus of an electrophotographic printer for developing an image on a photoreceptive drum includes a disc rotating independently of the photoreceptive drum at both sides of the photoreceptive drum and having at least one cam groove formed on an outer circumferential surface thereof. A developing unit includes a housing containing developer and a developing roller supported by both sidewalls of the housing and having a shaft contacting the outer circumferential surface of the disc. An elastic member is provided at a rear surface of the housing and presses the developing apparatus toward the photoreceptive drum. Thus, since the disc having at least one cam groove is provided on the outer circumferential surface and rotates independently of the photoreceptive drum, the developing roller can be detached from the photoreceptive drum at a predetermined pressure.

摘要： A sheet coating apparatus including a storage tank in which a coating liquid having charged coating particles dispersed therein is contained, a development roller rotatably installed to be immersed in the coating liquid, a voltage source for applying a voltage to the development roller, a coating roller rotatably installed in a state in which it is partially immersed in the coating liquid while maintaining a predetermined development gap relative to the development roller, and a compression roller for pressing a sheet passing between the compression roller and the coating roller toward the coating roller while securely rotating with respect to the coating roller. The coating particles adhere to the surface of the coating roller at the development gap due to an electric force to then be coated on the sheet passing between the coating roller and the compression roller. The sheet coating apparatus can prevent excess coating liquid from being coated on a sheet by regulating the amount of the coating liquid coated on the sheet, thereby attaining uniform coating.

摘要： An image forming apparatus for determining a state of conveying a printing medium and a method thereof are disclosed. The image forming apparatus includes a convey belt rotating in a caterpillar manner for conveying a printing medium to a photoconductor. A charge roller charges a printing medium that enters the convey belt. A convey roller faces the charge roller and forms a convey nib with the charge roller. A transfer unit transfers a developer image formed on the photoconductor to the printing medium. A resistance detector constantly detects resistance of the convey roller. A controller determines whether the resistance is varied within a reference time.
