  • Publication number: 20250153677
    Abstract: A vehicle front structure includes a hood, a storage part, and a support. The hood covers a vehicle front of a vehicle from above. The storage part is disposed below the hood and has a shape of a recess including a bottom wall, a front wall, and a rear wall. The support supports the bottom wall of the storage part from below. The support extends in a vehicle width direction of the vehicle and supports the storage part on a front side with respect to a front-rear center of the storage part. The storage part is configured to be bent such that a rear side of the bottom wall with respect to the support moves downward near a rear end of the support by an input from the hood upon a collision with a pedestrian.

  • Publication number: 20240345515
    Abstract: An image forming apparatus includes a fixing device to fix a toner image onto a recording material. The fixing device includes a heating unit, a pressure rotating member, a temperature detection unit, a storage unit, a reading unit, a sheet feeding unit, a conveyance unit, and a control unit. The pressure rotating member abuts the heating unit to form a nip portion. The storage unit stores information regarding a temperature rise rate of the fixing device. When the recording material is conveyed to the nip portion, the control unit controls the heating unit at a target temperature. Where a predetermined temperature lower than the target temperature is reached, the control unit controls the conveyance unit to start conveying the recording material from the sheet feeding unit to the nip portion. The control unit further determines the predetermined temperature based on the information read by the reading unit.
