Increase in nanoparticle due to the diesel engine exhaust and the secondary formation from atmospheric gaseous contaminants has been observed in the atmospheric environment. In indoor air, exposure to airborne particulate matters including ultrafine particles has an adverse health effects especially to respiratory tracts. There are previous works on the sources of indoor ultrafine particles, such as cooking, smoking, spraying, a scent candle burning, and laser printers. The measurement methods of particle emission rates from a copier or printer are specified in ISO standards, however it is difficult to evaluate the ultrafine particle emission rates by using this method. Since the discussion of ultrafine particle emission mechanisms is now going on, it is important to develop the emission chamber for printers, and analyze the chemical composition of emitted particles so as to clarify the particle formation mechanisms in the office equipments.
