Image forming apparatus

摘要

An image forming apparatus includes an image bearing member (1); a rotatable charging member (2), forming a nip with the image bearing member, for electrically charging the image bearing member; developing means (3) for developing an electrostatic image formed on the image bearing member to form a toner image, the developing means supplying electroconductive particles (m) to the image bearing member, to enhance changing wherein the electroconductive particles are fed to the nip by the image bearing member; transferring means (5) for transferring the toner image onto a recording material (P) at a transfer position; wherein the developing means is capable of feeding the electroconductive particles of a region of the image bearing member which corresponds to a region between a first recording material and a second recording material immediately subsequent to the first recording material, and a time period from passage of a trailing end of the first recording material through the transfer position to arrival of a leading end of the second recording material at the transfer position is longer than a time period required for the charging member to rotate one full-turn.
