Embodiment

[0120] Hereinafter, the present invention is described in more detail by means of specific examples. It should be noted that "parts" in the examples means "parts by mass".

[0121] (embodiment 1-14 and reference examples 1 and 2)

[0122] (1) Production and evaluation of conductive elastic rollers

[0123] (Production of conductive elastic roller 1)

[0124] Components (1), (2-1), (3), (4) and (5) in the amounts shown in Table 1 were kneaded in a 6-L kneader for 20 minutes. Next, ingredients (6) and (7) in the amounts shown in Table 1 were added to the mixture, and then the whole was further kneaded with an open roll for 8 minutes. Thus, a kneaded product I was obtained.

Abstract

Provided is a method of producing a member for electrophotography capable of providing a high-quality electrophotographic image. The method of producing a member for electrophotography is a method of producing a member for electrophotography having an electro-conductive support, an elastic layer, and a surface layer, the method comprising: a first step of forming, on a surface of the elastic layer, a coat of a surface-layer coating liquid containing a hydrolyzed condensate of a hydrolyzable silane compound and a chelate titanium compound represented by the following general formula (2); and a second step of crosslinking the hydrolyzed condensate in the coat through cleavage of an epoxy group in the hydrolyzed condensate to form the surface layer:

Description

technical field [0001] The present invention relates to a production method of a member for electrophotography and a coating liquid for forming a polysiloxane-containing film. Background technique [0002] In recent years, along with an increase in the speed of the process of forming an electrophotographic image, the time for the electrophotographic photosensitive member and the charging member to contact each other has become relatively short. This is detrimental to stabilizing and ensuring charging of the electrophotographic photosensitive member. PTL 1 describes that a surface layer formed from a surface layer coating liquid containing a condensate formed of a hydrolyzable silane compound and a hydrolyzable titanium compound increases the relative dielectric constant and improves the charging performance of the charging member.
