A minute-particle trapping device includes: an air duct having a duct space through which air containing minute particles flows; a first filter disposed to block the duct space in the air duct and having a honeycomb structure to trap the minute particles contained in the air; and a second filter disposed in the air duct at a position downstream from the first filter in an air flow direction to block the duct space, the second filter being formed from a nonwoven fabric folded in a wave pattern to trap minute particles contained in the air that has passed through the first filter.

A particle collecting device includes: an air pipe having a flow space in which air including particles flows; and a collecting unit that is disposed in such a way as to block the flow space of the air pipe and that collects the particles included in the air. The collecting unit is a plate-shaped air-permeable member having a honeycomb structure such that a number of cells per square inch is 600 or larger and 1400 or smaller.

A waste-developer collecting device includes a developing device that develops a latent image with developer, a storage section that stores the developer transported from the developing device, and a path section extending from the developing device to the storage section, and including a downward path through which the developer in the developing device flows together with air in the developing device, the downward path guiding the flowing developer downward. An opening is provided on an upper side and an upstream side of a lowermost level of the downward path so that a part of the air flowing in the path section is released out through the opening.

A cooling device that cools the inside of an image forming apparatus provided with a developer carrier that carries an image developed with a developer while being rotated. The cooling device includes: a counting unit that counts an accumulative number of rotation of the developer carrier; and a fan that cools the inside of the image forming apparatus. The cooling device further includes: a calculating unit that calculates an abrasion amount of the developer carrier in which the accumulative number of rotation counted by the counting unit is used as at least one variable; and a controlling unit that actuates the fan with cooling efficiency according to the abrasion amount calculated by the calculating unit.

It is a purpose of the invention to provide a dust protector for an image exposure device capable of preventing particles from sticking to windows or the like of the image exposure device and free from moisture condensation on the windows or the like of the image exposure device as a result of direct exposure of the same to the atmosphere and an image forming apparatus utilizing the same. The purpose is achieved by providing a dust protector for an image exposure device for performing image exposure on a member to be exposed from below with a dust protective member for preventing particles from sticking to at least a member located above an optical path of the image exposure device by covering the image exposure device from above without blocking the optical path of the image exposure device and an air flow generating unit for generating an air flow that prevents particles from entering the region covered by the dust protective member.
