摘要： An image forming apparatus includes a developer container, a development device, a developer replenishment device and a control part. The control part obtains a replenishment amount (X) of the developer replenished by the developer replenishment device from a last-time replenishment until a this-time replenishment and a predicted consumption (Y) of the developer, calculated based on the image data output from the last-time replenishment until the this-time replenishment, and informs abnormality when an absolute value of a difference of the replenishment amount (X) and the predicted consumption (Y) is larger than a threshold value.

摘要： In an inkjet recording apparatus, a control section forms a test chart in which a plurality of lines, each extending along the recording-medium width direction, are drawn arranged along the recording-medium conveyance direction by making the ink ejection nozzles eject ink, while gradually changing either ink ejection timing with respect to each of the ink ejection nozzles or a recording-medium conveyance speed. Furthermore, the control section checks for, and corrects, pixel deviation in the recording-medium conveyance direction based on the test chart.

摘要： An inkjet recording apparatus includes a conveyance section, a conveyance belt, a recording section, a suction fan, a current detection section, a recording-medium detection section, and a control section. After passage of a predetermined time since detection of presence of a recording medium performed by the recording-medium detection section, the control section makes a judgment on whether a drive current applied to the suction fan detected by the current detection section exceeds a first threshold value determined in advance, and in a case where the drive current applied to the suction fan does not exceed the first threshold value, the control section prohibits the recording section from ejecting ink.

摘要： An inkjet recording apparatus includes, among a plurality of branch conveyance passages, ones with different conveyance distances for a recording medium. Based on the timing of the sensing of the recording medium by a recording medium sensor, a controller controls a switching portion to make it switch the destination of the conveyance of the recording medium to one of the branch conveyance passages.

摘要： A control section of an inkjet recording apparatus forms a test chart between both ends of a recording medium in a recording-medium width direction by drawing a plurality of line sets, in each of which there are arranged a predetermined number of lines each extending in a recording-medium conveyance direction and each drawn with ink ejected from a single one of the plurality of ink ejection nozzles, by sequentially shifting the plurality of line sets by one line in the recording-medium width direction, each time the recording medium proceeds a predetermined distance in the recording-medium conveyance direction. Further, the control section detects, by using the detection section, presence/absence of ink on each of the plurality of lines drawn in the test chart, and determines presence/absence of a defective pixel, and a position of the defective pixel.

摘要： An ink jet recording apparatus includes a line head, a purging mechanism, a wiper blade, a blade moving mechanism, a waste liquid passage forming portion, and a maintenance control portion. The maintenance control portion performs a first maintenance process of allowing a cleaning liquid ejection nozzle to eject cleaning liquid without allowing ink ejection nozzles to eject ink, and then allowing the wiper blade to move from a first end edge to a second end edge on a liquid ejection surface, and a second maintenance process of allowing the ink ejection nozzles to eject ink while allowing the cleaning liquid ejection nozzle to eject the cleaning liquid, and then allowing the wiper blade to move from the first end edge to the second end edge on the liquid ejection surface, after the first maintenance process.

摘要： Provided is an image forming apparatus that performs smoothing in conversion of pseudo high resolution without using a large translation table. A smoothing process part performs smoothing based on a density of a peripheral pixel that adjoins a target pixel on edge. When a density change between both sides of the target pixel in a sub scanning direction is larger than a density change between both sides of the target pixel in a main scanning direction, a density of a plurality of pixels after conversion of pseudo high resolution of a sub scanning direction corresponding to the target pixel is mutually changed. Also, when a density change between both sides of target pixel in the sub scanning direction is not larger than a density change between both sides of the target pixel in the main scanning direction, the density set to the same.
