Problems solved by technology

However, since the negative polarity corona discharge used in the negative charging process is unstable and generates a larger amount of ozone than the positive polarity corona discharge, adverse effects on photoreceptors and adverse effects on the use environment have become question

Embodiment 1

[0201] A sheet-shaped photoreceptor for testing electrical properties and a drum-shaped photoreceptor for testing printing performance were prepared, respectively. Incidentally, the term "part" means part by weight.

[0202] The solution for undercoating prepared in the following manner was applied to each aluminum sheet (3cm×10cm, thickness: 1mm) and aluminum drum (outer diameter: 30mmφ, length: 247.5mm, thickness: 0.75mm), and then dried at 100°C for 60 minutes to remove the solvent. Thus, an undercoat layer having a film thickness of 0.3 μm was formed.

[0203] (preparation of solution for undercoating)

[0204] a1) Soluble nylon (AMILAN CM8000, manufactured by Toray Industries, Inc.): 3 parts by weight (30 g)

[0205] The aforementioned material a1) for the undercoat layer was stirred with 97 parts by weight (970 g) of a mixed solvent of methanol / methylene chloride (5 vol / 5 vol), and dissolved to prepare a solution for the undercoat layer.

[0206] Next, on top of this...

Embodiment 2

[0217] Prepare photoreceptors in the same manner as photoreceptor Example 1, the difference is that, for the composition of the dispersion liquid for the single-layer photosensitive layer in photoreceptor embodiment 1, 5 parts by weight of the previous general formula (I- The compound represented by 3) was replaced by 5 parts by weight of the compound represented by the foregoing general formula (I-83) [Synthesis Example 2].

Embodiment 3

[0219] Prepare the photoreceptor in the same manner as photoreceptor Example 1, the difference is that, for the composition of the dispersion liquid used in the monolayer photosensitive layer in Photoreceptor Example 1, the styrene-based compound represented by the previous general formula (HT1-101) The material is changed into 7 parts by weight from 8 parts by weight; the amount of compound represented by the preceding general formula (I-3) as electron transfer material is changed from 5 parts to 2 parts: the amount of bisphenol Z type polycarbonate resin is changed from 7 parts to 10 servings.

Abstract

A quinone-based compound having a structure represented by the following general formula (I): [wherein, R<1> to R<4>, R<5> and R<6 >represent an alkyl group or the like, an aryl group or the like, and a halogen atom or the like, respectively, X represents a sulfur atom or an oxygen atom, n represents an integer of 0 to 3, and when n is 2 or 3, R<6 >may combine with one another to form a ring or a condensed ring]; a photosensitive article for an electrophotography containing the compound in the photosensitive layer thereof; and an electrophotographic device using the article. The quinone-based compound is excellent in electron transporting function and thus is useful for a photosensitive article for an electrophotography and an organic EL application, and the photosensitive article is excellent in electric characteristics and is stable also when used repeatedly.

Description

technical field [0001] The present invention relates to quinone-based compounds. More specifically, the present invention relates to novel quinone-based compounds that can be used as electron transfer substances in electrophotographic photoreceptors (hereinafter simply referred to as "photoreceptors"), organic electroluminescence (EL) devices etc. The present invention also relates to an electrophotographic photoreceptor and an electrophotographic device, and more specifically, to an electrophotographic photoreceptor using a specific compound as an electron transfer substance, and to an electrophotographic device using such an electrophotographic photoreceptor. Background technique [0002] From the viewpoint of photoreceptor characteristics that can be designed due to the non-pollution, low cost, and free choice of materials or other viewpoints, in recent years, many organic photoreceptors using organic photoconductive materials have been proposed and put into practical use...
