Surface additive infrared taggant toner
A toner composition includes toner particles having a resin and a colorant, the composition further including an infrared luminescent taggant disposed on the surface of the toner particles. A method of making a toner composition includes toner particles having a resin and a colorant, the composition further including an infrared luminescent taggant disposed on the surface of the toner particles, the method includes blending toner particles with a surface additive package that includes the infrared luminescent taggant. An article includes a printed image disposed on the article, the printed image made with a toner composition including toner particles having a resin and a colorant, the composition further including an infrared luminescent taggant disposed on the surface of the toner particles, the printed image allowing authentication of the article by infrared detection of the infrared luminescent taggant.
ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PRODUCTION METHOD OF ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC APPARATUS
The present invention provides: an electrophotographic photosensitive member which can achieve both of abrasion resistance and electrical characteristics; a production method of the electrophotographic photosensitive member; and a process cartridge and an electrophotographic apparatus having the electrophotographic photosensitive member. A surface layer of the electrophotographic photosensitive member includes a cured product and a specific amount of an alcohol or carboxylic acid having a specific structure, wherein the cured product is a polymerized product of a hole transporting compound having an acryloyloxy group or a methacryloyloxy group.
ELECTROPHOTOGRAPHIC BELT AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS
An electrophotographic belt has a surface layer, wherein the surface layer includes 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 particles; 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 particles.
