Abstract
An object of the present invention is to provide an image forming apparatus that has an image bearing body, a flexible charging member constituting a nip portion together with the image bearing body, the nip portion being provided with conductive particles, and a developing member for developing an electrostatic image formed on the image bearing body, with use of a developing agent, wherein the developing agent has substantially spherical toner.
Claims17
An image forming apparatus comprising:
- an image bearing body;
- a flexible charging member constituting a nip portion together with said image bearing body, said nip portion being provided with conductive particles;
- a source for supplying said flexible charging member with a voltage of predetermined polarity to charge said image bearing body;
- and
- a developing member for developing an electrostatic image formed on said image bearing body, with use of a developing agent,
- wherein said developing agent has substantially spherical toner, such that residual spherical toner conveyed to said flexible charging member is chargeable by friction with the conductive particles to the same polarity as the predetermined polarity.
