摘要： A developing device includes a developing roller, a cover to cover the developing roller from above the developing roller, a filter to cover a vent of the cover to filter air and collect toner passing through the vent, and a pressing member engaged with the cover in which the filter is installed. The cover includes a projecting support to support the filter. The pressing member holds the filter between the pressing member and the cover. The projecting support is projected from one end toward the other end of the vent in a transverse direction of the vent at a part of the cover in a longitudinal direction of the developing roller to block the vent, and cantilevered on the one end. A gap is provided between a tip of the projecting support and an inner edge of the cover on the other end.

摘要： An image forming apparatus includes an image bearer, a rotation shaft, a developing device, and a supply portion. The developing device includes a developing device main portion that rotates around the rotation shaft between a developing position and a retracted position and includes a developer, a developer bearer to face or be away from the image bearer depending on whether the developing device main portion is at the developing position or the retracted position, a replenishment portion having a replenishment port with an opposite surface formed by an arc drawn around the rotation shaft to replenish the developer, and a non-rotating portion. The supply portion has a supply port with an opposite surface formed by an arc drawn around the rotation shaft and facing the opposite surface of the replenishment port. The supply port communicates the replenishment port and supplies the developer to the developing device through the replenishment port.

摘要： An image forming apparatus includes an image carrier, an image forming member, a transferer, a toner image detector, and a controller. The transferer transfers the toner image from the image carrier directly or indirectly onto a recording medium transported by a surface moving member. The toner image detector detects a test toner image formed in a test toner image detection area located at an end portion of the surface moving member. The controller checks a length of the recording medium in a main scanning direction during continuous image formation, and forms the test toner image either in a space between recording media when the length of the recording medium exceeds a length of the surface moving member minus a length of the test toner image detection area in the main scanning direction or otherwise in parallel to the toner image transferred onto the recording medium.

摘要： A development device includes a development casing, a developer bearer, a first developer conveyance member to supply developer to the developer bearer, a second developer conveyance member to transport developer axially, and a partition dividing an interior of the development casing into a supply channel and a collecting channel via which developer received from a downstream end portion of the supply channel is forwarded to an upstream end portion of the supply channel. The supply channel includes a conveyance area and a buffer area disposed adjacent to the conveyance area in a direction perpendicular to an axial direction to temporarily retain developer and midway in the developer conveyance direction inside the supply channel, and an upstream end face defining an upstream end of the buffer area is inclined relative to the axial direction to draw away from the conveyance area downstream in the developer conveyance direction.

摘要： An image forming apparatus includes a reference-pattern detecting transfer-body, a reference-pattern detecting unit, and a condition changing unit. The reference-pattern detecting transfer-body directly transfers a reference pattern image formed on an intermediate transfer body without a recording material. The reference-pattern detecting unit detects an optical reference pattern with respect to the image transferred onto the reference-pattern detecting transfer-body. The condition changing unit changes the image forming conditions based on a result of detection.
