Image forming apparatus

Abstract

An image forming apparatus having excellent chargeability, sensitivity and light responsivity of an electrophotographic photoconductor and capable of forming images of high quality and high resolution at a high speed in various circumstances, is provided. An electrophotographic photoconductor having a photosensitive layer containing the enamine compound represented by the following general formula (1), for example, the enamine compound represented by the following structural formula (1-1) as a charge transportation substance is mounted to an image forming apparatus and the volume average particle size of the toner contained in a developer 50 housed in a developing device 33 is set to a size from 4 to 7 mu.

Description

technical field

[0001] The present invention relates to an electrophotographic image forming apparatus such as a copying machine. Background technique

[0002] An electrophotographic image forming apparatus (hereinafter referred to as an electrophotographic apparatus) that forms an image using an electrophotographic technique is often used as a copying machine, a printer, or a facsimile apparatus. In the electrophotographic apparatus, an image is formed by the following electrophotographic process. First, the photosensitive layer of the electrophotographic photoreceptor (hereinafter referred to as "photoreceptor") installed in the device is uniformly charged to a predetermined potential by a charging device such as a charging roller, and the exposure device is used to perform exposure in accordance with the image information to form static electricity. latent image. A developer is supplied to the formed electrostatic latent image, and a toner which is a component of the de...
