To provide a transparent or nonblack polyimide resin composition having a stable medium resistivity value at normal temperature and humidity to high temperature and humidity with slight fluctuation of the resistivity values due to variation between samples, a change in amount added and a change in voltage and environment, excellent mechanical characteristics and excellent antistatic properties by transportation, transferability and fixing properties in an electrophotographic machine and easily cleaning a toner sticking by misprints in a transfer belt or a fixing belt, etc.
This polyimide resin composition comprises 100 pts.wt. of a polyimide resin and 5-200 pts.wt. of potassium titanate and/or aluminum borate. The polyimide resin composition has a volume resistivity value within the range of 1×109 to 1×1015 Ωcm.
