Abstract

Provided is a transfer belt (1) which is capable of implementing a high transfer property even for a recording medium (1000) having concave-convex portions on the surface and suppressing degradation in an image grade by repetitive use. The transfer belt (1) transfers a toner image carried on a first main surface (1a, 21s1') onto a recording medium (1000) and includes at least an elastic layer (3). When the transfer belt (1) is pressed by pressing force at a predetermined pressing speed and then pressed by constant pressing force using a lower block (110) including a curved convex surface (112) having a hole section (113) formed therein and an upper block (120) including a curved concave surface (122), if a maximum value of displacement in a measurement region (MR) which is a portion corresponding to the hole section (113) in the first main surface (1a, 21s1') is indicated by "a" [µm], and displacement of the measurement region (MR) after the displacement of the measurement region (MR) converges is "b" [µm], E [-] calculated by (a - b)/b using "a" and "b" satisfies a condition of 0.2 ¤ E ¤ 3.
