Abstract
The present invention relates to an image forming apparatus with a charging member which charges an image bearer with a photoconductive surface. Forming a layer containing ferroelectric as part on the charging member, and applying the electric field formed by dipoles of the ferroelectric, the photosensitive member surface is electrified, thereby downsizing a charger and reducing power consumption thereof are achieved for realizing low-cost and reducing the number of consumable parts sufficiently.
Claims19
An image forming apparatus, including a charging member for electrifying to an image bearer which has a photoconductive surface, comprising;
- the charging member arranged opposing to the image bearer and having a layer containing a ferroelectric at least as part thereof, and
- the ferroelectric subjected to a dipole orienting treatment in advance, wherein the photoconductive surface of the image bearer is electrified by an electric field formed by the dipoles of the ferroelectric.
