Abstract
A coating liquid for an electrophotographic photoconductor intermediate layer comprising a titanium oxide and a polycarboxylic acid polymer in a solvent is provided. The content of the polycarboxylic acid polymer is 0.3 to 10 parts by weight in respect to 100 parts by weight of the titanium oxide, and an acid value of the polycarboxylic acid polymer is 30 to 400 mgKOH/g.
Claims3
An electrophotographic apparatus comprising:
- an electrophotographic photoconductor;
- a charger configured to charge the electrophotographic photoconductor;
- a light irradiator configured to irradiate the electrophotographic photoconductor with a light to form an electrostatic latent image on the electrophotographic photoconductor;
- an image developer configured to develop the electrostatic latent image with a developer comprising a toner to form a toner image on the electrophotographic photoconductor;
- a transfer configured to transfer the toner image onto a receiving material;
- and
- a fixer configured to fix the toner image on the receiving material;
- wherein said electrophotographic photoconductor comprises at least an intermediate layer and a photosensitive layer on an electroconductive substrate, and said intermediate layer contains a titanium oxide and a polycarboxylic acid polymer.
A process cartridge for an electrographic apparatus comprising an intermediate layer which comprises a titanium oxide and a polycarboxylic acid polymer, and a photosensitive layer on an electroconductive substrate.
