Image forming apparatus

An image forming apparatus, comprising:

• a power supply part that supplies electronic power in a power mode that is chosen from two different power modes that are a first mode and a second mode wherein a power consumption in the second mode is smaller than a power consumption in the first mode,
• a communication part that includes:
• a transmitting and receiving part that receives a network packet in both the first mode and the second mode;
• and
• a determination part that
• stores filter information containing a plurality of filter settings and
• determines whether or not the network packet, which is received by the transmitting and receiving part in the second mode, matches one of the plurality of filter settings, creating a determination result;
• a determination control part that performs a rewrite operation to repeatedly rewrite the filter information in the determination part while running in the second mode;
• a power supply control part that transits the power mode of the power supply part from the second mode to the first mode based on the determination result of the determination part;
• a packet transmitting and receiving part that
• receives the network packet supplied from the transmitting and receiving part in the first mode and
• stops an operation of itself in the second mode;
• and
• an image forming part that
• forms an image on a recording medium based on the network packet received by the packet transmitting and receiving part in the first mode and
• stops an operation of itself in the second mode.
