Image formation apparatus using an electrophotographic process |
摘要 |
An image formation apparatus using an elecrophotographic process for obtaining a high quality image with tone value R<2 >of equal to or more than 0.98 is provided. The resolution for light-writing is equal to or more than 1200 dpi and/or light-writing is performed based on image data formed by applying halftone processing at a line frequency of equal to or more than 200 lpi. Light-writing means is accomplished with a laser light beam with a beam diameter equal to or more than 35 mum. The photoconductor includes a charge generating layer containing a charge generating material and a charge transfer layer containing a charge transfer material laminated on a conductive support. The ionization potential of the charge generating material Ip(CG) and ionization potential of the charge transfer material Ip(CT) satisfy the relationship of Ip(CG)>=Ip(CT).
