    Abstract: A cleaning device includes a separation and contact mechanism and a controller. The controller includes a separation and contact control unit, a conveyance roller rotation control unit, and a take-up control unit. The separation and contact control unit controls the separation and contact mechanism so as to allow the web to be pressed to the conveyance roller when the conveyance roller is in a non-conveyable state. The conveyance roller rotation control unit rotates the conveyance roller at a cleaning rotational speed lower than a conveyance-time rotational speed of the conveyance roller in a conveyance state. The take-up control unit allows the take-up roller to perform a take-up operation of taking up the web corresponding to a rotation of a take-up roller plural times at a predetermined time interval within a cleaning time in a state where the conveyance roller is being rotated at the cleaning rotational speed.

    Abstract: A sheet guide of an image forming apparatus includes a first upstream guide member and a first downstream guide member. The first upstream guide member includes an upstream front guide surface and an upstream rear guide surface. The first downstream guide member includes a downstream front guide surface and a downstream rear guide surface. The downstream front guide surface intersects with an imaginary plane formed by extending, toward a downstream side in a conveyance direction of a sheet, the upstream rear guide surface. The upstream front guide surface intersects with an imaginary plane that is formed by extending, toward an upstream side in the conveyance direction, the downstream rear guide surface. When viewed from a direction perpendicular to the upstream rear guide surface, an edge portion of the first upstream guide member on the downstream side is inclined with respect to a width direction perpendicular to the conveyance direction.

    Abstract: An image forming apparatus includes an image carrier, a developing section, a transfer section, a pre-transfer conveyance passage, and a guide member. The pre-transfer conveyance passage allows conveyance of the sheet from the developing section to the transfer section. The guide member defines a side of the pre-transfer conveyance passage that faces the transfer surface. The guide member includes: a guide body having a guide surface that faces the transfer surface of the sheet; and a tip section having a curved portion joining an end edge of the guide body, and a distal edge that is on a downstream side in the conveyance direction and faces the image carrier. The distal edge is located at such a position as to allow the transfer surface of the sheet to lie at a space therefrom when a leading end of the sheet is in contact with the image carrying surface.

    Abstract: An inkjet recording apparatus includes a sheet feed section, an image forming section, a partition unit, an air inflow portion, a first sheet conveyance section, a second sheet conveyance section, and an air sucking and discharging section. The partition unit partitions an interior of an apparatus casing into a first space in which the image forming section is disposed and a second space in which the sheet feed section, the first sheet conveyance section, and the second sheet conveyance section are disposed. Air outside the apparatus casing is taken into the first space through the air inflow portion. The second sheet conveyance section includes a conveyance guide disposed downstream of the image forming section in a conveyance direction of a recording sheet. The air sucking and discharging section sucks air around the conveyance guide and discharges the air into the second space or out of the apparatus casing.

    Abstract: A conveyor device includes a guide member with through holes therein. The guide member has a surface with grooves therein. The through holes are located inside of the grooves. The through holes include a first through hole and a second through hole. The first through hole is located opposite to an ejection region of a recording head. The second through hole is located opposite to a non-ejection region of the recording head. The grooves include a first groove and a second groove. The first through hole is located inside of the first groove. The second through hole is located inside of the second groove. The second groove is longer than the first groove.

    Abstract: A conveyor device is disposed opposite to a recording head. The conveyor device includes a conveyor belt and a suction section. The suction section sucks on a recording medium through the conveyor belt. The suction section includes an air flow chamber and a guide member. The air flow chamber is disposed opposite to one surface of the conveyor belt, and negative pressure for sucking the recording medium onto another surface of the conveyor belt is created in the air flow chamber. The guide member covers the air flow chamber and supports the conveyor belt. The air flow chamber includes a partition wall dividing the air flow chamber into first and second spaces. The first space includes a third space overlapping with the recording head with the conveyor belt and the guide member therebetween. Pressure in the first space is less negative than pressure in the second space.
