摘要： An approach is provided for applying a release agent to a substrate having a first surface and a second surface. The approach involves determining a presence of at least one ink image applied to at least one portion of one of the first surface and the second surface of the substrate by way of one or more steps of a printing process. The approach also involves determining the substrate is to be made ready for printing one or more other images on the other of the first surface and the second surface by one or more steps of another printing process. The approach further comprising causing, at least in part, the release agent to be applied to the substrate so as to cover the at least one portion of the first surface and the second surface of the substrate upon which the at least one ink image is applied at a time before the substrate is subjected to the one or more steps of the another printing process.

摘要： An image forming apparatus according to one aspect of the present disclosure includes an image forming portion, a curling correction portion, and a speed control portion. The image forming portion forms an image on a recording medium. The curling correction portion has one pair of rollers composed of members that respectively have different elasticities and are pressed against each other, and corrects curling that has occurred in the recording medium after image formation performed thereon by the image forming portion, by conveying the recording medium sandwiched with the roller pair. The speed control portion changes a conveyance speed of the recording medium by the roller pair based on a density value of an image formed on the recording medium.

摘要： An image-forming device includes a casing, a conveying path, a pair of registration rollers, and a process cartridge. The conveying path is disposed in the casing to convey a recording sheet. The pair of registration rollers is disposed on the conveying path to regulate a leading edge of the recording sheet conveyed along the conveying path. The process cartridge is detachably mounted on the casing, and includes a developer accommodating unit, a photosensitive member, and an upstream guide part. The photosensitive member is disposed on the conveying path. The upstream guide part is disposed upstream of the pair of registration rollers on the conveying path to guide the recording sheet toward the pair of registration rollers in cooperation with the conveying path. The upstream guide part is formed with a concaved part that is concaved in a direction away from the conveying path.

摘要： To provide an image forming apparatus in which the paper is cooled early by blowing air to the paper in the conveying path so as to prevent a sticking phenomenon on a paper output tray while paper turning, paper folding, paper breakage and paper jamming due to influence on paper conveyance by blowing air onto the paper in the conveying path, can be prevented. At the start of paper conveyance, a gate 73 is turned upwards to a first position to thereby close a sixth conveying path 44 and establish communication between a first conveying path 42 and a second conveying path 43 so that the paper having passed through a fixing unit 21 starts to be conveyed from first conveying path 42 to second conveying path 43. At the same time, air is exhausted from an exhausting mechanism 53 arranged upstream of a cooling mechanism 76. When a first paper sensor 74 detects the leading end of the paper, a cooling fan 77 starts to rotate at a predetermined rotational rate to start blowing air at a predetermined volume of cooling airflow.

摘要： According to the present invention, skew feeding of a sheet is corrected while conveying the sheet, positioning of a side edge of the sheet in the width direction is carried out, and an image is formed on the sheet by an image forming portion 90. Two steering mechanisms 120a and 120b are disposed upstream of the image forming portion along the conveying direction, and the steering mechanisms 120a and 120b can feed a sheet on the skew in any direction with respect to the sheet conveying direction. Two CISs 100a and 100b are disposed along the sheet conveying direction corresponding to the steering mechanisms. A skew feeding angle and a skew feeding velocity of each of the steering mechanisms is changed according to differential value between a side edge position detected by the CISs 100a and 100b and a target position of a side edge of a sheet.
