The present invention relates to an inkjet image forming apparatus capable of
recording non-margin images on a recording medium by discharging ink from a recording
head to regions within as well as beyond edges of the recording medium. The apparatus
includes an ink absorbing material for receiving ink discharged at a position beyond
the recording medium and a platen having a holding portion to hold the ink absorbing
material and supporting the recording medium at a recording position. The holding
section formed at the platen has an opening for receiving the ink and is formed
with a wall for holding a periphery of the ink absorbing material and a rib supporting
a bottom of the ink absorbing material.
