Image forming apparatus
First Claim
Patent Images
1. An image forming apparatus comprising an image bearing member;
- a charging means for charging the image bearing member, to which charging means is applied a charging voltage including a first alternating component; and
a developing means for developing an electrostatic image formed on the image bearing member with developer, to which developing means is applied a developing voltage including a second alternating component; and
wherein 10<
PS/|Hz1-Hz2| is satisfied where Hz1 (Hz) indicates a frequency of the first alternating component, Hz2 (Hz) indicates a frequency of the second alternating component, and PS (mm/sec) indicates a peripheral speed of the image bearing member.
