There is provided an inkjet recording apparatus having a cleaning device, which can securely remove ink on a conveying belt having no negative effects on conveyance accuracy. The inkjet recording apparatus for forming an image on a recording medium includes a conveying belt for supporting and conveying a recording medium, a recording head for forming an image by jetting ink onto the recording medium conveyed by the conveying belts, and a cleaning device having a cleaning roller provided in pressure-contact with the conveying belt and driven to rotate in the same direction as the conveying direction of the conveying belt, wherein, the cleaning roller is set to rotate at a surface linear speed thereof lower than a conveying speed of the conveying belt.

An image recording apparatus for recording an image on a recording medium includes a conveying belt for supporting and conveying the recording medium, and a recording head for recording the image by jetting ink onto the recording medium. The apparatus further includes a plurality of cleaning rollers for cleaning the conveying belt, the cleaning rollers being in pressure-contact with the conveying belt, and a plurality of cleaning liquid baths for respectively storing cleaning liquid to be used to remove dirt deposited on the respective cleaning rollers and for dipping the respective cleaning rollers into the cleaning liquid. The apparatus uses liquid waste as cleaning liquid in a cleaning liquid bath on an upstream side of the conveying belt, the liquid waste having become unable to be used in a cleaning liquid bath on a downstream side of the conveying belt any longer as cleaning liquid.

Image recording apparatus

The present invention concerns an image recording apparatus, which records images on a roll-type recording medium. The image recording apparatus includes a recording device to record an image on a recording medium by emitting ink onto the recording medium; a cutting member to cut the recording medium after the recording device records the image, the cutting member being disposed downstream in respect to the recording device in a conveying-direction of the recording medium; a second conveyance member to convey the recording medium, the second conveyance member being disposed at a position located between the recording device and the cutting member in the conveying-direction of the recording medium; and a conveyance controller to control the second conveyance member so as to generate a slack of the recording medium at a section between the recording device and the second conveyance member in the conveying-direction of the recording medium.

An inkjet recording apparatus is provided with a recording head to conduct recording by jetting an ink onto a recording medium having an ink receiving layer containing thermoplastic in particles on a surface thereof and a pigment ink solvent absorbing layer adjoining to an inner side of the ink receiving layer; a heating and pressing device to heat and press the recording medium so as to make the ink receiving layer of the recording medium to be transparent; a conveyor to convey the recording medium to the recording head and further to the heating and pressing device; and a temperature controller to control a heating temperature by the heating and pressing device within a range of T &plusmn;&Dgr;T&deg; C., where T is 50 to 150&deg; C. and &Dgr;T is not larger than 10&deg; C.

A film image editor for editing plural photographic film images. The editor includes: a scanner for reading images in any one of a plurality of different picture sizes from a developed photographic film; a picture size detecting circuit for detecting a picture size of each of the images based on a density variation information of each of the images; an editing interface for editing the image in the detected picture size according to an input operation by an operator; and an output device for outputting the image which is edited by the editing interface.

Film image editing apparatus using image density variation detection

The color image forming machine such like a color printer or a color copier for forming a color image on a recording sheet. The image forming machine includes a photoreceptor belt; a belt driver for rotating the photoreceptor in a longitudinal direction; a laser beam scanner for repeatedly scanning the photoreceptor in a direction perpendicular to the longitudinal direction, with the laser beam, so that the latent image is formed on the photoreceptor; a developer for developing the latent image with plural color toners; a measuring unit for determining a rotation time of the photoreceptor; and a controller unit for controlling a scanning frequency of the laser beam scanner so that one scanning time of the laser beam scanner is set to the result of dividing the rotation time of the photoreceptor, while the photoreceptor rotates one round, by an integer.
