Color inkjet recording apparatus and copier with increased reliability

A color inkjet recording apparatus comprising:

• a plurality of multi-nozzle inkjet recording heads, wherein each recording head is elongated to cover a width of a recording medium, has thousands to tens of thousands of nozzles corresponding thereto arranged with densities of 400 to 2400 dpi, and ejects ink on demand at frequencies of a few to 30 kHz per nozzle, the multi-nozzle inkjet recording heads being arranged and fixed so as to eject a plurality of color inks supplied from an ink container provided below said multi-nozzle inkjet recording heads;
• a separation part separating the color inkjet recording apparatus into a first region in which said ink container is provided and a second region in which the rest of the color inkjet recording apparatus is provided;
• and
• a holding part configured to hold the ink container, the holding part including a plurality of separation parts,
• wherein the recording medium includes a surface on which recording is performed and has the recording surface coated with particulate matter,
• the recording is performed by conveying the recording medium to a position that opposes surfaces of said multi-nozzle inkjet recording heads, said surfaces including the nozzles and ejecting ink droplets from the nozzles onto the recording surface of the recording medium,
• the ink container includes a plurality of independent ink containers containing the respective color inks, and
• the holding part holds the independent ink containers so that the independent ink containers are separated from each other.
