Abstract:
1. An electrophotographic device comprising: a developing toner, comprising a rice wax and a carnauba wax; a photoreceptor; an optical unit forming an electrostatic latent image on the photoreceptor; a development unit visualizing the electrostatic latent image on the photoreceptor with the developing toner to form a visualized toner image; a transfer unit transferring the visualized toner image onto a recording medium; a fixing unit fixing the toner image transferred from the transfer unit on the recording medium to obtain a recording image; and a cleaning unit removing a residual toner on the photoreceptor and having a cleaning blade which comes into press contact with the photoreceptor in a low load state, wherein the developing toner satisfies at least one of equations (1) and (2): wherein X is an absolute value of charge amount of the developing toner (μC/g), wherein Y is a deposition amount of the developing toner (mg/cm wherein the carnauba wax and the rice wax are blended in a mixing ratio from 1/10 to 10/1, and wherein the developing toner has a weight average particle size in a range of from 4 μm to 10 μm.
