    摘要： An oil application roller capable of preventing an oil leak when the roller is left in the state where the rotation axis thereof runs vertically and also capable of preventing an oil escape from the roller in a fixing device. The oil application roller (15) includes a seal ring (25) at respective end portions of the roller (15). The seal ring (25) includes a vent hole (26) extending from an end face of the roller (15) to the outside of the seal ring (25), and the cross-sectional area of the vent hole is not less than 0.01 mm2 and not more than 1 mm2.

    摘要： An image forming apparatus such as an electrophotographic copying machine includes an optical system for housing a scanning exposure optical system. The optical system housing is composed of surrounding walls having ends joined in pairs in interdigitating relationship, one of the ends in each of the pairs having an end surface held in abutment against an inner surface of the surrounding wall having the other end. An image forming mechanism is housed in an image forming mechanism housing having a pair of confronting side walls spaced from each other. One of the side walls is taller than the other side wall, and has support fingers projecting laterally from an inner surface thereof. The optical system housing is supported on the support fingers and the other side wall.

    摘要： An image forming apparatus such as an electrophotographic copying machine includes an optical system for housing a scanning exposure optical system. The optical system housing has air inlet and outlet holes for introducing air into and discharging air from the optical system housing. The air outlet holes have an opening area greater than an opening area of the air inlet holes. Electrostatic filters are mounted on the optical system housing in covering relation to the air inlet and outlet holes. Thus, the optical system housing is substantially closed. The optical system housing is composed of surrounding walls having ends joined in pairs in interdigitating relationship, one of the ends in each of the pairs having an end surface held in abutment against an inner surface of the surrounding wall having the other end. An image forming mechanism is housed in an image forming mechanism housing having a pair of confronting side walls spaced from each other. One of the side walls is taller than the other side wall, and has support fingers projecting laterally from an inner surface. The optical system housing is supported on the support fingers and the other side wall.
