Title: Image forming apparatus
Inventor: TANAKA MASANOBU
IPC: G03G15/00
Filed: 2020-09-03
Abstract: To prevent, with a simple configuration, a rear end of a recording material from moving toward a fixing film when the recording material passes through a fixing device.SOLUTION: Before a rear end of a recording material passes through a fixing nip part, a control unit decreases a rear conveyance speed Ve of a conveying device compared with a fixing conveyance speed Vf of a fixing device (S3) to make a relative speed difference ΔV smaller than 0 (ΔV<0). This makes it possible to convey the recording material while bending it toward a pressure roller between the fixing device and the conveying device in a state in which the recording material is sandwiched by both the fixing device and the conveying device. When the recording material is conveyed while bending it toward the pressure roller in this way, the rear end of the recording material can be prevented from moving toward a fixing film when the recording material passes through the fixing nip part. Consequently, the rear end of the recording material does not come too close to the fixing film, and thus spark discharge does not occur in part of a surface of the fixing film.SELECTED DRAWING: Figure 4
