Image forming apparatus

An image forming apparatus, comprising:

• an exposing unit;
• a first processing component configured to generate print data and register setting data, the print data causing the exposing unit to blink in accordance with image data, and the register setting data that is referred to in exposing processing of the exposing unit based on the print data;
• and
• a second processing component including a register to which the register setting data is set and connected to the first processing component through a first signal line, the second processing component configured to receive the print data and the register setting data from the first processing component, and to perform blink control of the exposing unit based on the print data and the register setting data,
• wherein the exposing unit is connected to the second processing component through a second signal line;
• the second processing component configured to select the register setting data that corresponds to the print data and, thereafter, execute the blink control of the exposing unit based on the print data and in accordance with a blink mode set by the register setting data, and start exposure of the exposing unit based on the print data inputted thereto, and
• after the second processing component starts the exposure processing of the exposing unit based on preceding print data inputted, the first processing component starts outputting a part of the register setting data that corresponds to a succeeding print data, and, after the second processing component terminates the exposure processing of the exposing unit based on the preceding print data, the first processing component outputs the succeeding print data and the remaining part of the register setting data.
