Abstract: A heating roller driving device for a heating roller of an image forming apparatus. The heating roller driving device includes a motor for supplying the heating roller with a driving force for the heating roller to contact or separate from a photosensitive belt. A motor controller is provided for controlling the operation of the motor, and a main controller is included for providing the motor controller with a predetermined command to operate the motor. A lever is pivotably installed on the shaft of the heating roller for moving the heating roller to contact or separate from the photosensitive belt, a roller gear is installed at one end of the shaft of the heating roller for receiving the driving force transferred from the motor, a clutch is installed at a predetermined location in the vicinity of the heating roller for pushing the lever or for releasing the lever from the pushed state to in turn move the heating roller to contact or separate from the photosensitive belt by the driving force transferred from the motor, and a plurality of motor gears is installed on the output shaft of the motor for selectively transferring the driving force of the motor to either the roller gear or the clutch depending on a position of the clutch and in turn the heating roller. Since the heating roller is moved to contact or separate from the photosensitive belt by a single motor, the driving device has advantages in that the entire system structure can be simplified and the manufacturing cost of the apparatus can be lowered.

Abstract: A color registration adjusting method in an image forming apparatus includes the steps of determining whether the detected pulse width for the edge of a photoreceptor belt is smaller than the expected pulse width thereof. If the detected pulse width is smaller than the expected pulse width, then the detected pulse width is set as a scanning start signal (an edge signal mixed) and a value obtained by subtracting a predetermined value from the currently expected pulse width is set as the next expected pulse width. Alternatively, if the detected pulse width is greater than or equal to the expected pulse width in the first step, the expected pulse width is set as the scanning start signal and a determination is made whether the counted value of a pulse is smaller than an offset value. If the pulse counted value is smaller than the offset value in the step, a value obtained by subtracting a predetermined value from the currently expected pulse width is set as the next expected pulse width. Alternatively, if the pulse counted value is greater than or equal to the offset value, a value obtained by adding a predetermined value to the currently expected pulse width is set as the next expected pulse width. Since some of the next expected pulse widths are determined by comparing the pulse counted value and offset value, the mis-registration of color in the main scanning direction of a laser beam can be adjusted quantitatively.

The printer includes a photoreceptor belt circulating along a path formed by a plurality of rollers; a plurality of optical scanning devices for scanning light toward the photoreceptor belt; a plurality of developing devices for supplying developing materials of different colors to the photoreceptor belt; a plurality of detectors for detecting part of light emitted from the optical scanning devices; an engine controller for controlling the driving of the optical scanning devices, the developing devices, and the rollers, based on received light output from the optical detectors, so that test patterns for each optical scanning device set to detect the color registration error between the optical scanning devices can be formed on the photoreceptor belt; a pattern position detector for detecting the positions of the test patterns formed from fixed positions through a developing process; and a color registration correction calculator for calculating a color registration error amount from the position information of the test patterns provided by the pattern position detector, and calculating color registration correction data from the calculated error amount and outputting the calculated correction data to the engine controller. In color registration error correction using the printer, the positions of electrostatic latent images, corresponding to test patterns formed on a photoreceptor belt by optical scanning devices, are detected by developing the electrostatic latent images with a single color. Therefore, a structure for measuring error amounts from the test patterns is simple, and the accuracy of measurement can be improved.
