An image forming apparatus that executes processes necessary for image formation in a distributed manner. An image forming module (304) executes a process assigned by a sub master control unit (330) and a slave control unit (331) which are connected to each other by a pair of serial communication buses (380tx, 380rx). The sub master control unit (330) transmits first data for executing a process assigned to the slave control unit (331) via the serial communication bus (380tx). The slave control unit (331) transmits second data to the sub master control unit (330) via the serial communication bus (380rx) in a period during which the slave control unit (331) does not receive the first data. |
