PROBLEM TO BE SOLVED: To provide an image formation apparatus which improves image quality over a long period while simplifying the apparatus configuration.SOLUTION: A compound machine 11 includes an image formation unit 15 forming an image. The compound machine 11 includes a photoreceptor, a charging roller, an electrification bias voltage application unit 39, an LSU 31, a development unit, a development bias voltage application unit 39, a cleaning blade, and a control unit 12. The photoreceptor is a positive charge type and has a single-layered resin photosensitive layer. The charging roller is a rubber charging roller for electrifying the photoreceptor. The electrification bias voltage application unit 39 applies the electrification bias voltage for electrifying the photoreceptor to the charging roller. The cleaning blade is a rubber cleaning blade for removing toner remaining on the photoreceptor. The rebound resilience modulus of the cleaning blade is equal to or less than 35%. The molecular weight of resin constituting the photosensitive layer is equal to or greater than 50000. The voltage applied by the electrification bias voltage application unit 39 is the DC voltage.SELECTED DRAWING: Figure 2 |
