Abstract: A developing apparatus includes an electrostatic latent image bearer, a developing sleeve, a case, and an air filter. The case accommodates a two-component developer and the developing sleeve. The air filter is attached to the case. The air filter has a thickness of 2 to 20 mm and has a density gradient with a pressure loss of 2 to 40 Pa at a wind speed of 10 cm/s. The air filter forms an airflow sucked into the case from a gap between the developing sleeve and the case and forms an airflow discharged from the case through the air filter. The two-component developer accommodated in the case contains a magnetic particle a surface of which is coated with a resin layer. The resin layer contains at least one type of chargeable particle.

Abstract: A slave apparatus control portion refers to a priority channel table stored in a use priority channel memory at the time of establishing communications with a host apparatus. The radio channel having the highest priority is allocated as the initial channel, and a connection request signal is transmitted from a communicating portion to the host apparatus in the frequency band of the initial channel. When the initial channel interferes with the radio channels used by other slave apparatuses or the frequency bands used by PCs, the radio channel overlapping those frequency bands is avoided, and the radio channel of the frequency band that is the second highest priority is selected.
