Microparticle collecting device and image forming apparatus

The present invention provides a microparticle collection device and the like capable of collecting and reducing at least ultrafine particles having a large particle size from among ultrafine particles having a particle size of 100 nm or less contained in air. A fine particle collection device (6) is provided with: a breather pipe (61) having a flow path space (61a) through which air containing fine particles flows; an airflow generation unit (62) that generates an airflow flowing in the air conveying direction (C) in a flow path space (61a) of the breather pipe (61); and a collection section (63) that is disposed so as to traverse the inside of the flow path space (61a) of the breather pipe (61) and collects fine particles contained in the air, the collection section (63) being configured from a metal breather plate having a plurality of breather sections (63a) having an opening size of 0.005-0.1 mm (inclusive). 本发明提供一种微粒子捕集装置等，其能够捕集并减少空气中所含的粒径为100nm以下的超微粒子中的至少粒径较大的超微粒子。微粒子捕集装置(6)具备：通气管(61)，其具有供包含微粒子的空气流动的流路
