  • Publication number: 20250147453
    Abstract: When the dimension of a primary transfer roller in the width direction is represented by Wa, the dimension of a counter-sensor member in the width direction is represented by Wb, the dimension of an intermediate transfer belt in the width direction is represented by Wc, and the maximum dimension of a sheet in the width direction is represented by Wd, then the relationship Wd?Wa<Wb?Wc is fulfilled. The transfer position of a test pattern image is a position a predetermined distance away, inward in the width direction, from the edge of the intermediate transfer belt in the width direction. The predetermined distance is twice or more the distance in the width direction from the edge of the intermediate transfer belt in the width direction to the edge of the primary transfer roller in the width direction.

  • Patent number: 12286324
    Abstract: A post-processing apparatus includes a blade, a transfer mechanism, a sheet folding roller pair, a motor, a drive control device, and a control device. The blade presses into the sheet to form a fold line in the sheet. The transfer mechanism moves the blade toward and away from the sheet. The sheet folding roller pair conveys the sheet with the fold line formed by the blade by pinching the sheet at a nip between the sheet folding roller pair. The motor rotatively drives the sheet folding roller pair. The drive control device controls drive of the motor. The control includes a control circuit. When, through the processor executing a control program, the control device controls the transfer mechanism to withdraw from the nip the blade having been pressed into the sheet and the nip by the transfer mechanism, the control device controls the drive control device to stop the motor.
