摘要： An imaging apparatus that is capable of realizing good cleaning characteristics and transfer characteristics, and obtaining a high quality image using toner having a high average roundness is provided. The imaging apparatus includes an image carrier, a charge unit, a developing unit, a transfer unit, and a cleaning unit. The transfer unit may directly transfer a toner image onto a recording medium that is carried by a transfer belt, or transfer the toner image onto the transfer belt first to then transfer the toner image onto the recording medium from the transfer belt. The cleaning unit includes a cleaning blade and a brush roller. The toner used in the imaging apparatus has an average roundness Ψ within a range of 0.93˜0.99, and a friction coefficient μs of the image carrier satisfies a condition, friction coefficient μs≦3.6−3.3×average roundness Ψ.

摘要： An image forming apparatus that can prevent the generation of filming with the simplest possible configuration even if a plurality of photosensitive member linear velocities are provided and the AC frequency of the charge apparatus is fixed. A charge apparatus that charges by uniformly superimposing on a photosensitive member an alternate current bias voltage with a fixed frequency over a direct current bias voltage as the charge bias voltage; an exposure apparatus that exposes the surface of the charged photosensitive member based on image data, and writes a latent image; a developing apparatus that supplies toner to and makes visible the latent image formed on the surface of the photosensitive member; a transfer apparatus that transfers the visible image on the photosensitive member to a transfer medium; and a cleaning apparatus that cleans the surface of the photosensitive member after transfer. The image forming apparatus further comprises a filming removal mode that removes filming on the surface of the photosensitive member; and the filming removal mode is selected corresponding to the plurality of photosensitive member linear velocities.
