Abstract: A cleaning device includes a sheet conveyance roller, and a cleaning unit that cleans a surface of the sheet conveyance roller. The cleaning unit includes a cleaning member that can come in contact with the surface of the sheet conveyance roller, and a pressing roller that presses the cleaning member against the surface of the sheet conveyance roller. The pressing roller includes a low Young's modulus area formed at least on a part of the pressing roller in a radial direction, the low Young's modulus area having a Young's modulus lower than a Young's modulus of the sheet conveyance roller. When the surface of the sheet conveyance roller is cleaned, the pressing roller is pressed against the sheet conveyance roller so as to elastically deform in the radial direction in a state where the cleaning member is sandwiched between the pressing roller and the sheet conveyance roller.

Abstract: The cleaning device includes a cleaning unit. The cleaning unit includes a cleaning part having a contact surface brought into contact with a surface of a conveyance roller to clean the surface of the conveyance roller, and a housing that supports the cleaning part. The cleaning part includes a web of a strip shape, the web forming the contact surface that comes in contact with the conveyance roller, a pressing roller that presses the web against the conveyance roller, a feed-out roller that feeds out the web so as to cause a part of the web that comes in contact with the conveyance roller to shift, and a take-up roller that takes up the web. The housing has an opening that receives foreign matter dropping from the vicinity of a nip portion formed between the pressing roller and the conveyance roller.

Abstract: A decurling device includes a first conveyance path, a second conveyance path, a first switch, a decurler, and a controller. A sheet is conveyed along the first conveyance path or the second conveyance path. The first switch switches a route of conveyance of the sheet to the first conveyance path or the second conveyance path. The sheet has a first main surface and a second main surface. The decurler is located in the second conveyance path. The decurler corrects curl of the sheet. In a situation in which a weight per unit area of the sheet is smaller than a first threshold value, the controller controls the first switch such that the sheet is conveyed along the second conveyance path.

Abstract: A de-curling device de-curls a sheet and includes an endless belt, a de-curling roller, a nip width adjusting mechanism, and a belt tension adjusting mechanism. The endless belt is looped around a pair of supporting rollers. The de-curling roller is provided between the pair of supporting rollers and has a first outer circumferential surface pressed against a second outer circumferential surface of the endless belt to form a nip portion at which the endless belt curves along the first outer circumferential surface, the de-curling roller being configured to de-curl the sheet passing through the nip portion. The nip width adjusting mechanism adjusts the nip width by moving the de-curling roller in a direction intersecting the second outer circumferential surface of the endless belt. The belt tension adjusting mechanism adjusts the tension of the endless belt according to the nip width adjusted by the nip width adjusting mechanism.

Abstract: An inkjet recording apparatus includes memory, a processor, an image forming section, and a bending mechanism. The memory stores therein bending information in which a plurality of bending amounts corresponding to respective ejection amounts of an ink ejected from the image forming section are defined. The processor sets a bending amount of a sheet to be conveyed. The bending mechanism includes a roller and a belt that hold the sheet therebetween, and bends the sheet by moving a position of a center of the roller toward the belt based on the set bending amount. The processor calculates for each of areas of the sheet an amount of the ink ejected to the area, and sets the bending amount of the sheet based on the bending amounts corresponding to the calculated amounts of the ink ejected to the respective areas in the bending information.

Abstract: A cleaning device cleans a conveyance face of a conveyance member conveying a sheet. The cleaning device includes a delivery roller, a pressure roller, a fixed roller and a winding roller. The delivery roller supports a web roll that a belt shaped web is wound into a roll. The pressure roller brings the web delivered from the web roll into pressure-contact with the conveyance face. The fixed roller keeps an extending angle of the web passed from between the conveyance member and the pressure roller constant. The winding roller winds the used web passed the fixed roller into a roll.

Abstract: A cleaning device cleans a surface of a sheet conveyance member which conveys a sheet in an image forming apparatus that executes image forming processing using a recording material, the surface carrying a solid substance that originates from the recording material and that adheres to the surface. The cleaning device includes a cleaning member including a contact surface configured to come in contact with the surface of the sheet conveyance member. The contact surface is an irregular surface rougher than the surface of the sheet conveyance member. At cleaning of the surface, the cleaning member makes a relative movement to the surface of the sheet conveyance member. The irregular surface is an irregular surface configured to take away the solid substance adhering to the surface of the sheet conveyance member when the cleaning member makes the relative movement.
