Description

ABSTRACT:
Rollers between which an endless belt is wound have a pair of first grooves looping around a rotational axis of each roller. A pair of second grooves is formed in an upper face of a support plate that supports an inner face of the endless belt, these second grooves extending along an entire length of the support plate in a feeding direction of the printing sheet. Each of the first grooves and the second grooves are disposed so as to be in the same straight line. First ink absorbers are provided that absorb ink within the first grooves. Second ink absorbers are provided that absorb ink within the second grooves. Protruding rails are formed on the inner face of the endless belt and fit into the first grooves and the second grooves. These first and second grooves prevent feeding accuracy of printing sheets from deteriorating.
