Image forming apparatus

An image forming apparatus comprising:

• an image bearing member;
• a rotatable charging member, forming a nip with said image bearing member, for electrically charging said image bearing member;
• developing means for developing an electrostatic image formed on said image bearing member to form a toner image, said developing means supplying electroconductive particles to said image bearing member, wherein the electroconductive particles are fed to the nip by said image bearing member;
• transferring means for transferring the toner image onto a recording material at a transfer position;
• wherein said developing means is capable of feeding the electroconductive particles of a region of said 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 variable in accordance with a number of recording materials continuously passing through the transfer position.
