Electrophotographic belt, electrophotographic image forming apparatus, and method for manufacturing electrophotographic belt
An electrophotographic belt is provided, which includes a base layer and a surface layer in direct contact with the base layer, wherein the surface layer includes heteroaggregates of a first particle and a second particle, the first particle is at least one selected from the group consisting of a hollow silica particle and a solid silica particle, and has a number-average particle diameter of primary particles, which is greater than 30 nm and less than 100 nm, the second particle contains a conductive metal oxide, and has a number-average particle diameter of primary particles, which is 5 nm to 40 nm, the surface layer has protruded portions derived from the heteroaggregates on an outer surface opposite to the surface facing the base layer, an arithmetic mean height (Sa) of the outer surface is 0.1 m to 0.7 m, and the base layer includes specific cation and anion.
IMAGE FORMING APPARATUS
First and second cover portions are arranged above a loading tray and below a transfer belt and overlap a loading surface and the transfer belt. When the loading tray in an extension state moves from a pulled-out position to a mounted position, the second cover portion moves in a mounting direction by movement of the loading tray. When the loading tray in the extension state is located in the mounted position, a protruding portion of the loading tray is located downstream of the housing in the mounting direction, and the second cover portion covers the protruding portion from above. When the loading tray is located in the mounted position, at least a part of the second cover portion has an area located downstream of a first cover downstream end in the mounting direction and overlapping the transfer belt and the loading surface, viewed in the direction of gravitational force.
ELECTROPHOTOGRAPHIC MEMBER, ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS AND METHOD OF PRODUCING ELECTROPHOTOGRAPHIC MEMBER
An electrophotographic member having a base layer and a surface layer in direct contact with the base layer is provided, in which the surface layer contains heteroaggregates of first particles and second particles different from the first particles, the first particles are chain-like inorganic oxide particles, the second particles contain a conductive metal oxide, the number-average particle diameter of primary particles is 5 to 40 nm, the surface layer has protruded portions derived from the heteroaggregates on an outer surface thereof opposite to a surface that faces the base layer, an arithmetic mean height (Sa) of the outer surface is 0.1 to 0.7 m, and the base layer contains specific cations and anions.
