Sliding member for fixing device, fixing device, and image forming apparatus

A sliding member for a fixing device comprising in order:

• a first fluororesin layer having a sliding surface dotted with recessed portions;
• a substrate;
• and
• a second fluororesin layer,
• wherein the recessed portions dotted in the sliding surface in the first fluororesin layer satisfy the following (1) and (2):
• (1) the recessed portions show an array pattern obtained by shifting some or all of points of central portions in a lattice array from the lattice array obtained by continuously arranging basic arrays including a basic lattice that is configured by four lattice points and has one side parallel to a sliding direction and a point of a central portion of the basic lattice,
• each of the basic arrays is configured such that no recesses other than recesses corresponding to the four grid points and the central point exist inside a perimeter defined by the four grid points, and
• (2) on the sliding surface, except both side portions thereof, at least one recessed portion is present on any straight line parallel to the sliding direction of the sliding surface.
