Abstract: A cleaning device includes a cleaning unit and a unit moving mechanism. The cleaning unit brings a web into contact with a conveyance member rotating around an axis and removes foreign matter adhered to the conveyance member. The unit moving mechanism displaces the cleaning unit to a cleaning position where the web is brought into contact with the conveyance member and to a separation position where the web is separated away from the conveyance member. When the unit moving mechanism displaces the cleaning unit from the cleaning position to the separation position, the cleaning unit is displaced in a counter direction opposite to a rotational direction of the conveyance member on a contact face between the conveyance member and the web.

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: An image forming apparatus includes a recording head, a controller, and a correction processor. The controller determines a nozzle corresponding to an image to be printed, and causes the recording head to eject ink from the nozzle. The correction processor detects an abnormally ejecting nozzle out of the nozzles in the recording head, and designates the abnormally ejecting nozzle as a target nozzle, and performs correction processing based on a status of the target nozzle, to the image. The correction processor also adds the detected abnormally ejecting nozzle to history data, each time a detecting operation is performed, and selects a nozzle included in the history data as an additional target nozzle, out of the nozzles that have not been detected as the abnormally ejecting nozzle, through the current detecting operation, and adds the selected nozzle to the target nozzle.

Abstract: A cleaning device includes a cleaning unit which removes foreign matter adhered on a conveyance face of a conveyance member conveying a sheet, by using a belt shaped web; and a unit moving mechanism which displaces the cleaning unit to a cleaning position where the cleaning unit comes into contact with the conveyance face and to a separation position separated away from the cleaning position. The cleaning unit includes a delivery roller delivering the web, a pressure roller bringing the web pressure-contact with the conveyance face and a winding roller winding the web passed the conveyance face. The cleaning unit is tilted such that a cleaning face of the web between the pressure roller and the winding roller faces upward as the cleaning unit is displaced from the cleaning position to the separation position.

Abstract: The head (8) of an ink discharge device (1) discharges ink into a recording medium being conveyed. A movement unit (12) moves the head (8) in the height direction (Z-axis direction) when the printing surface of the recording medium is set as the front surface. A controller (10) sets a discharge time gap, which is the gap between the nozzle (81) and the printing surface during ink discharge, in accordance with the image to be printed and the recording medium. The controller (10) causes the movement unit (12) to move the head in the Z-axis direction so as to reach the set discharge interval.
