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.

An image forming apparatus includes a main body, a feeder, and a relay device. The main body forms an image on a sheet. The feeder feeds the sheet toward the main body. The relay device connects the main body to the feeder. The main body is placed on a placement surface. The feeder is arranged opposite to the main body with the relay device therebetween in a direction along the placement surface. The relay device includes a conveyance unit and a casing which houses the conveyance unit. The conveyance unit conveys the sheet fed from the feeder to the main body and rotates relative to the casing with an axis as a pivot thereof. The axis extends in a cross direction intersecting with the placement surface.

In an image forming apparatus, a conveyance section forms a conveyance path and conveys a sheet in a conveyance direction. The conveyance section includes a conveyance roller for rotating around a roller shaft extending in a direction orthogonal to the conveyance direction, and a guide member. The guide member includes a first guide member for rotating around a first axial line to open/close with respect to a first partial region of the conveyance path, and a second guide member for rotating around a second axial line to open/close with respect to a second partial region different from the first partial region. The first axial line extends in a direction parallel to a longitudinal direction of the roller shaft. The second axial line extends in a direction intersecting with the longitudinal direction. The first guide member opens in conjunction with an opening action of the second guide member.

An inkjet recording apparatus includes an image forming section, a heater, a first calculation section, storage, and a second calculation section. The image forming section ejects ink onto a sheet in which first to M-th regions are defined (M is an integer of at least 2). The heater heats an n-th region of the sheet using an n-th heat source (n is an integer of at least 1 and no greater than M). The storage stores therein temperature information indicating a first heating temperature for the n-th region. The second calculation section calculates a second heating temperature for the n-th region based on the temperature information and the ink ejection amount to the n-th region calculated by the first calculation section.

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.

An inkjet recording apparatus () includes an image forming section (), a decurler (), a changing section (), a first calculating section (), storage (), a second calculating section (), and a controller (). The image forming section () ejects ink onto a sheet (S). The decurler () bends the sheet (S). The changing section () changes a bending amount of the sheet (S). The first calculating section () calculates an ink ejection rate (&#x3b1;) to the sheet (S) for each of areas of the sheet (S). The storage () stores therein first bending information () indicating a first target bending amount (&#x3b2;) of a specific area of the sheet (S) corresponding to the ink ejection rate (&#x3b1;) to the specific area. The second calculating section () calculates a second target bending amount of each of the areas. The controller () controls the changing section () based on the second target bending amounts.

An inkjet recording apparatus includes an image forming section, a roller, a heat source, a calculator, a determination section, and a controller. The determination section determines to activate the heat source when an ink ejection amount calculated by the calculator is larger than a specific reference amount. When the determination section determines to activate the heat source, the controller activates the heat source. When temperature of the roller is equal to or higher than a specific temperature, the controller controls the image forming section to form the image on the sheet.

A decurling device includes a decurler. The decurler includes a first dryer roller, a second dryer roller, and a heat source. The heat source is disposed at the first dryer roller to heat the first dryer roller. The first dryer roller and the second dryer roller rotate while holding a sheet therebetween to convey the sheet.

Decurling device and inkjet recording apparatus

An inkjet recording apparatus includes an image forming section, a heater, a calculation section, storage, and a determination section. The image forming section ejects ink onto a sheet in which first to M-th regions are defined (M is an integer of at least 2). The heater includes first to M-th heat sources and heats an n-th region of the sheet using an n-th heat source (n is an integer of at least 1 and no greater than M). The calculation section calculates an ink ejection rate of ink to be ejected onto the n-th region. The storage stores therein heating information indicating whether it is necessary to heat the n-th region. The determination section determines whether or not to cause the n-th heat source to generate heat.

A decurling device includes a belt, a roller, and a heat source. The heat source heats either or both of the belt and the roller. The belt has a first holding surface extending in a rotational direction of the belt. The roller has a second holding surface extending in a rotational direction of the roller.

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.
