An image forming apparatus includes: a hardware processor that forms an image on a conveyed recording medium; and a determining device that determines whether a type of the recording medium is a first recording medium or a second recording medium, wherein if the type of the recording medium is determined to be the first recording medium, the hardware processor forms a normal image on the recording medium, whereas if the type of the recording medium is determined to be the second recording medium, the hardware processor forms a test image on the recording medium.

Image forming apparatus and image forming method

An image recording device includes a recorder, a reader and a hardware processor. The recorder records an image on a recording medium. The reader reads, with an imaging element, a surface of the recording medium and a surface of a predetermined reference member. The hardware processor calibrates the reader for a value to be detected by the imaging element, based on a reading result of the reading of the surface of the reference member. Further, the hardware processor performs the calibration in at least one of: a case where a type of the image to be recorded on the recording medium satisfies a predetermined image type condition; and a case where a predetermined reading influence factor which affects a reading result of the reading of the surface of the recording medium satisfies a predetermined reading influence factor condition.

An inkjet recording device includes an image forming drum, a recording medium supplying section, a recording head which ejects ink onto a recording medium, a first heating unit which heats the recording medium held on the drum before image recording, a second heating unit which heats the drum downstream of the position at which the recording medium is outputted after image recording and upstream of the supplying section, a heating-unit temperature detector, a drum temperature detector, and a heating control section. The heating control section performs heat control of the first heating unit such that the temperature detected by the heating-unit temperature detector falls within a predetermined set temperature range, and performs heat control of the second heating unit such that the temperature detected by the drum temperature detector falls within a predetermined set temperature range.
