徴とする記録装置。[Claims for Utility Model Registration] 1. A device that forms an electrostatic latent image on a photoreceptor, develops the electrostatic latent image with toner in a developing section, and transfers the obtained toner image to a recording member in a transfer section. forming a sensor pattern image on a part of the photoreceptor in the axial direction, detecting the density of the sensor pattern image,
In the recording device that adjusts the amount of toner supplied to the developing section, the transfer section includes a transfer charger that applies charges of the same polarity to the photoreceptor and the toner image, and a transfer charger that neutralizes the charges on the photoreceptor and the recording member. and a separate charger, wherein the transfer charger uniformly charges the photoreceptor, and the separation charger neutralizes the charge in areas other than the sensor pattern image forming area of the photoreceptor. Recording device. 2 Utility Model Registration The recording device according to claim 1, further comprising conductive cleaning means disposed at the rear of the transfer section.
