Embodiment Construction

[0030] Hereinafter, an image forming apparatus according to an exemplary embodiment of the present disclosure will be described in more detail with reference to the accompanying drawings.

[0031] 1. Configuration and Operation of Image Forming Apparatus

[0032] figure 1 is a schematic cross-sectional view of the image forming apparatus 1 according to the first exemplary embodiment. The image forming apparatus 1 according to the present exemplary embodiment is a tandem-type multifunction peripheral (including functions of a copier, a printer, and a facsimile apparatus) that employs an intermediate transfer system and can form a full-color image using an electrophotographic system.

[0033] like figure 1 As shown in , the image forming apparatus 1 includes an apparatus main body 10 , a reading device 80 , a feeding unit 90 , an image forming unit 40 , a discharge unit 48 , a control unit 30 , and an operation unit 70 . Temperature sensor 71 that can detect internal temperat...

Abstract

The invention discloses an image forming apparatus. The image forming apparatus includes an image bearing member that can bear a toner image, a transfer member for transferring the toner image from the image bearing member onto a recording material, and a reading device that reads density information of the image on the recording material disposed on a platen. The image forming apparatus forms a first chart on a first recording material and a second chart on a second recording material by sequentially transferring a plurality of test images while applying a plurality of test voltages to a transfer member. The reading device reads the two charts and adjusts the transfer voltage based on the read result.

Description

technical field [0001] The present disclosure relates to image forming apparatuses such as copiers, printers, or facsimile apparatuses using electrophotographic systems and electrostatic recording systems. Background technique [0002] Image forming apparatuses using an electrophotographic system have conventionally included an intermediate transfer system image forming apparatus that primarily transfers a toner image formed on an image bearing member such as a photosensitive drum to an intermediate transfer system such as an intermediate transfer system. onto the intermediate transfer member of the transfer belt, and then the toner image is secondarily transferred from the surface of the intermediate transfer member to the recording material. The primary transfer is performed by applying a primary transfer voltage to the primary transfer portion where the image bearing member and the intermediate transfer member are in contact. Secondary transfer is performed by applying a...
