Electrophotographic belt and electrophotographic image forming apparatus

An electrophotographic image forming apparatus comprising an electrophotographic belt having a surface layer as an intermediate transfer belt, wherein

• the surface layer comprises a (meth)acrylic resin, a porous-spherical particle, and an electroconductive particle different from the porous-spherical particle;
• in an outermost surface of the surface layer, a surface of the porous-spherical particle is coated with the (meth)acrylic resin and the electroconductive particle;
• the ten-point average roughness Rz (according to JIS B 0601-1994) of the outermost surface of the surface layer is 0.5 times or larger and smaller than 2 times an average primary particle diameter of the porous-spherical particle;
• and
• an average spacing between local peaks S (according to JIS B 0601-1994) on the outermost surface of the surface layer is 4 times or larger and smaller than 30 times the average primary particle diameter of the porous-spherical particle.
