A developing device includes a developing unit, a rotating member that rotates in a predetermined direction to generate an airflow in a space that accommodates the developing unit, and first and second partitioning members. The first partitioning member is disposed between the developing unit and the rotating member, and has first and second openings that are each provided with an opening-closing mechanism and respectively disposed at upstream and downstream sides in a direction of the airflow generated when the rotating member rotates in the predetermined direction. The second partitioning member is disposed between the developing unit and an external space, and has third and fourth openings that are each provided with an opening-closing mechanism and respectively disposed at downstream and upstream sides in the direction of the airflow generated when the rotating member rotates in the predetermined direction.

Developing device, image forming apparatus, and airflow controlling device

A developing device includes a developing unit; an airflow generator that generates an airflow in a space accommodating the developing unit; a partitioning member that has at least two openings located upstream of the developing unit in a direction of the airflow and that divides a region in which the developing unit is present from a region in which the developing unit is not present, the two openings being located at an upstream position and a downstream position in the direction of the airflow, at least the opening at the upstream position being provided with an opening-closing mechanism; and an element that performs at least an exothermic process in the space accommodating the developing unit.

Developing device and image forming apparatus

An image forming apparatus includes: a fusing unit that heats a toner image and fixes the toner image on a recording medium; an exhaust passage that allows air heated by the fusing unit to flow and discharges the air to an outside of the apparatus; a delivery unit that moves the air in the exhaust passage in a discharge direction; a target structural component to which the air is to be delivered; a ventilation passage that connects a portion on a downstream side of the delivery unit of the exhaust passage in the discharge direction and the target structural component, and that allows the air to flow; and an adjuster that adjusts a passage through which the air flows, at a branch point between the exhaust passage and the ventilation passage.

Image forming apparatus

A sheet material feeding device comprises a sheet material housing part housing a sheet bundle having a plurality of sheet being stacked; a conveying-out unit press-contacting onto the front edge side of the upper surface of the sheet bundle to exert a push-out force, feeding a sheet by the push-out force in a predetermined conveying-out direction, and separating the sheet from the sheet bundle; a feeding unit arranged on the downstream side of the sheet material housing part along the conveying-out direction and continuing the feeding of the sheet, and after the conveying-out unit moves away from the rear edge of a preceding sheet, the conveying-out unit conveys a following sheet in a state that the following sheet is overlapped at the lower side of the preceding sheet until the front edge of the following sheet reaches a predetermined guide position set between the sheet bundle and the feeding unit.

A noise suppressor in an image forming apparatus suppresses noise from a drive mechanism during operation. An operation start signal of the drive mechanism is detected. A previously stored secondary sound having a reversed waveform to the waveform of the noise is generated at a noise suppressing position based on the drive operation start signal.

An electrostatic recording head comprises an insulating substrate having a builtup structure thereon. The builtup structure includes, in the following order, a plurality of dielectric electrode strips having portions which are arranged in parallel to and kept away from one another, a first insulating layer, a plurality of discharge electrode strips each extending to intersect with the respective portions of the dielectric electrode strips, a second insulating layer having a plurality of openings to form part of an ion generating space region at individual intersected portions of said discharge electrode strips and said dielectric electrode strips, and a screen electrode which is provided to complete each ion generating space region in association with the second insulating layer and has a plurality of openings, through which ions are passed, corresponding to the respective ion generating space regions. The screen electrode is made of a member which is selected from the group consisting of metals, noble metals and alloys mainly composed of these metals and which has a melting point not lower than 1500.degree. C. Alternatively, the screen electrode may be made of a core member and a surface layer which is made of the above metal member, or an oxidation-resistant material such as an inorganic compound, a polymer or a metal alkoxide polymer.
