CPC G03G 15/55 (2013.01) [G03G 15/5016 (2013.01)] | 23 Claims |
1. An image forming apparatus, comprising:
an image bearing member;
a charging roller configured to charge the image bearing member;
an exposure component configured to form an electrostatic latent image on a surface of the image bearing member;
a developing device configured to develop the electrostatic latent image formed on the surface of the image bearing member into a toner image;
a transfer roller configured to transfer a toner image from the image bearing member;
a controller configured to detect a resistance detection voltage of the transfer roller as a voltage for indicating that an abnormality exists in the image bearing member; and
a detector configured to detect the resistance detection voltage, resulting in a detected resistance detection voltage,
wherein the controller is further configured to:
determine whether or not the abnormality exists in the image bearing member based on the detected resistance detection voltage,
detect a waveform corresponding to a temporal change in the resistance detection voltage for each rotation of the image bearing member, resulting in a detected waveform, and
determine whether or not the abnormality exists in the image bearing member based on the detected waveform.
