Abstract: An image forming apparatus includes a laser scanner unit configured to deflect a laser beam with a reflection surface of a polygon mirror to scan a photosensitive drum, an engine controller, and an image controller. The engine controller generates an image formation BD signal synchronized with a BD signal output from the laser scanner unit. The image controller masks an assertion period of the image formation BD signal, and determines a specific reflation face based on the masked assertion period. The image controller sets a mask period of the image formation BD signal at the time of the specific reflation face to be longer than a mask period at the time of another reflation face. The image controller corrects image data based on the identified reflection face to control image forming processing.

There is provided a layer change unit configured to, if the images overlap each other, intuitively change the hierarchical level of an image to perform processing for an image hidden behind another image, thereby allowing processing for the image hidden behind the other image by changing the hierarchical level of the image while maintaining its position without moving the image.

Abstract: An image forming apparatus capable of performing control so as to prevent a line registration error from occurring, even if a timing to start counting a positional deviation becomes different between color plane images. A BD identification unit of the image forming apparatus identifies whether a main scanning sync signal is a sync signal for odd-numbered line or for even-numbered line, and outputs a first or second timing edge signal. According to the timing edge signal, a sub-scan timing controller controls an output timing of an image signal to a printer controller. When the top of a page is detected based on the timing edge signal first input from the BD identification unit, the sub-scan timing controller is made enabled. If the first timing edge signal is subsequently input, the image signal output timing is controlled according to the second timing edge signal which is next input.

Abstract: An image processing controller suspends an operation of hardware when receiving instructions of an interrupt of an event that should be executed with higher priority than rendering, such as a copy job, during execution of rendering by the hardware. Then, an information processing controller executes the rendering, which was being executed by the hardware, by software. Accordingly, even if an interrupt to suspend the operation of the hardware occurs during rendering by the hardware, the rendering can be completed as quickly as possible without waiting for restart of the operation of the hardware.
