    摘要： An object is to provide an image forming process, an image forming apparatus, and a color electrophotographic print that can provide a color electrophotograph that has a sufficient density in its dark area, has gloss, has a high glossiness over the entire densities covering bright areas (a white area and a highlight area), areas at intermediate densities, and dark areas (a black area and a shadow area) and can achieve high image quality equivalent to silver halide photographs. An image forming process produces an electrophotographic print which has a black density of 2.0 or more, a black color satisfying the following condition in the CIE 1976 (L*a*b*) color space: (a*)2+(b*)2≦9, and a 20-degree minimum glossiness of 60 or more.
