Abstract
An image forming apparatus using an electrophotographic process including a photoconductor, a development device, and a transfer device, a measuring device measures an electrostatic capacitance between said photoconductor and said transfer device in predetermined conditions while a standard toner image is formed. Humidity of ambient environment is also measured. Then, a controller controls image forming conditions such as a development condition or a transfer condition according to the measured electrostatic capacitance and the humidity. Alternately, a resistance of the paper is measured, and a controller controls image forming conditions according to the measured resistance. In a still different way, an amount of toner charges of a standard toner image is measured, and a controller controls image forming conditions according to the measured amount of toner charges.
