Abstract
A cleaning blade is disposed in an abutting relation with an image bearing body and configured to remove residual developer material from the image bearing body. The cleaning blade has a tan δ peak temperature equal to or higher than 8.6° C. and lower than 45° C., and any one of a Young's modulus equal to or higher than 13 Mpa and lower than 140 Mpa, a tensile strength equal to or higher than 37.3 Mpa and lower than 76 Mpa, a hardness equal to or higher than 83° and lower than 97°, and a tearing strength equal to or higher than 59 kgf/cm and lower than 118 kgf/cm.
