1. An image forming apparatus, comprising:
an image forming unit configured to form an image on a sheet using a developing material;
a communication device configured to communicate with a second device and including a processor configured to control communication with the second device; and
a controller configured to control the image forming apparatus to operate in a first power saving state, a second power saving state, and a normal state, wherein
in the first power saving state, the image forming unit and the controller are not activated, and the communication device is activated,
in the second power saving state, the image forming unit is not activated, and the communication device and the controller are activated, and
in the normal state, the image forming unit, the communication device, and the controller are activated, wherein
the processor of the communication device is configured to:
activate the image forming unit and the controller if data is received that is an instruction for sequential operation when in the first power saving state,
activate the controller if data is received that is not an instruction for sequential operation when in the first power saving state, and
transfer data to the controller when received in the second power saving state.
