Image forming apparatus and image forming method |
| abstract |
In an image forming apparatus, a cleaning member is pressed against a circumferential surface of an image bearing member and collects a toner remaining on the circumferential surface of the image bearing member. The toner has a number average roundness of 0.965 to 0.998. The toner has a D50 of 4.0 μm to 7.0 μm. A linear pressure of the cleaning member on the circumferential surface of the image bearing member is 10 N/m to 40 N/m. The image bearing member includes a single-layer photosensitive layer containing a charge generating material and a hole transport material. Ionization potential IpHTM of the hole transport material and ionization potential IpCGM of the charge generating material satisfy mathematical formula (1) “IpHTM≥5.30 eV”, mathematical formula (2) “IpCGM≥5.30 eV”, and mathematical formula (3) “0.09 eV≤|IpHTM−IpCGM|≤0.30 eV”. |
