摘要： An LD switch is turned ON to output image data outputted from an image processing section to a laser diode, and to irradiate a laser light to a photosensitive drum. The number of pixel dots included in the image data outputted from the image processing section is computed by line basis to detect an image density based on the total sum of the pixel dots of each color at a timing when the image data of Nth line is outputted from the image processing section. The detected image density is compared with a threshold value to turn OFF the LD switch at a timing when the image data of (N+α)th line is outputted when the image density is greater than the threshold value. This suppresses a variation in a rear-end-void length due to sheet slippage.

摘要： An image forming apparatus includes a controller for detecting the opening and closing of a shutter from the output from an optical sensor and controlling the opening and closing operation of the shutter based on the detected result. The controller determines that if the optical sensor is turned “ON” within a predetermined period of time from when the shutter begins opening, the operation of the shutter from the closed state to the open state is correctly detected. When no reflected light is detected by the optical sensor even after a predetermined time has elapsed, the controller determines that an anomaly has occurred and closes the shutter and repeat another detecting process.

摘要： A sub CPU of an image forming section forms a toner image based on test line data on an intermediate transfer belt, detects an inclination of the formed toner image for each color component, calculates an adjustment indicative value for correcting the detected inclination for each color component, and outputs the adjustment indicative values to the BK adjusting section, C adjusting section, M adjusting section, and Y adjusting section, respectively, of an inclination adjusting section. The BK adjusting section, C adjusting section, M adjusting section, and Y adjusting section generate, based on the respective adjustment indicative values obtained from the sub CPU, adjustment amounts for an inclination adjustment process to be executed on image data, execute the inclination adjustment process based on the generated adjustment amounts, and output the obtained image data to the respective LDs of an exposure unit.
