Abstract:
1. An electrophotographic image forming apparatus comprising: a photosensitive member of which a surface layer contains a compound of which at least one polymerization functional group has been hardened by electron irradiation; image forming means for forming a toner image on said photosensitive member; heating means for heating said photosensitive member; temperature detecting means for detecting a temperature of said photosensitive member; controlling means for controlling an operation of said heating means in accordance with an output of said temperature detecting means so that the temperature of said photosensitive member maintains a target temperature; temperature/humidity detecting means for detecting an ambient temperature and humidity; and setting means for setting the target temperature in accordance with an output of said temperature/humidity detecting means; an intermediate transfer member for transferring the toner image transferred from said photosensitive member to a recording material; auxiliary heating means for heating said intermediate transfer member; temperature detecting means for detecting a temperature of said intermediate transfer member; controlling means for controlling an operation of said auxiliary heating means in accordance with a detected temperature of said intermediate transfer member so that the temperature of said intermediate transfer member maintains a target temperature; and setting means for setting the target temperature of said intermediate transfer member at a temperature equal to or higher than the ambient temperature and equal to or lower than the target temperature of said photosensitive member.
