FIELD: image forming device.
SUBSTANCE: group of inventions relates to an image forming device and method of its control, which can implement mode with low power consumption. In the device main controller sends a request change mode with low power consumption subcontroller, if condition is satisfied for changing the state mode state of normal operating conditions on the state mode with low power consumption, and subcontroller copies program service with low power consumption, stored in the first memory in the second memory if received request change mode with low power consumption, and performs maintenance with low power consumption by executing the program of service with low power consumption by means of access to the second memory.
EFFECT: simplified design.
