PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC APPARATUS - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18178070 Titled 'PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC APPARATUS'
Simplified Explanation
The abstract describes a process cartridge used in an electrophotographic apparatus. The cartridge includes an electrophotographic photosensitive member, a toner, and a developing member. The electrophotographic photosensitive member has a surface layer made of a polymerized film composed of monofunctional (meth)acrylic compounds and tri- or higher functional (meth)acrylic compounds. The toner contains toner particles and hydrotalcite particles as an external additive. The hydrotalcite particles are analyzed to contain fluorine in filter fitting analysis of STEM-EDS analysis.
Original Abstract Submitted
The process cartridge is a process cartridge to be removably mounted onto a main body of an electrophotographic apparatus, the process cartridge including: an electrophotographic photosensitive member; a toner; and a developing member, wherein the electrophotographic photosensitive member includes a surface layer that is a polymerized film of a composition containing at least one kind of monofunctional (meth)acrylic compound selected from the group consisting of: a monofunctional (meth)acrylic monomer; and a monofunctional (meth)acrylic oligomer, and at least one kind of tri- or higher functional (meth)acrylic compound selected from the group consisting of: a tri- or higher functional (meth)acrylic monomer; and a tri- or higher functional (meth)acrylic oligomer, wherein the toner contains a toner particle and a hydrotalcite particle as an external additive, and wherein the hydrotalcite particle contains fluorine in filter fitting analysis of STEM-EDS analysis.
