Abstract
An image forming apparatus has an intermediate transfer member to which an image on an image bearing member is primarily transferred. The image primarily transferred to the intermediate transfer member is secondarily transferred to a recording medium. The velocity at which the recording medium is conveyed is switched to a velocity different from the image forming velocity before the recording medium is conveyed to the transfer position.
Claims14
An image forming apparatus comprising:
- an image bearing member;
- an intermediate transfer member to which an image formed on the image bearing member is transferred;
- a secondary transfer member configured to transfer the image that was transferred on the intermediate transfer member to a recording medium;
- a conveying unit configured to convey the recording medium to a transfer portion formed by the intermediate transfer member and the secondary transfer member;
- and
- a control unit configured to control the speed at which the recording medium is conveyed by the conveying unit,
- wherein the control unit is configured to convey the recording medium to the transfer portion at a first speed, higher than a speed at which the intermediate transfer member is moved, and to convey the recording medium at the first speed for a predetermined time after the recording medium reaches the transfer portion.
A method for controlling conveyance of a recording medium in an image forming apparatus, the apparatus having an intermediate transfer member to which an image on an image bearing member is transferred, the image transferred to the intermediate transfer member subsequently being transferred to a recording medium by a secondary transfer member, the method comprising the steps of:
- conveying the recording medium at a first speed, higher than a speed at which the intermediate transfer member is moved, to a transfer portion formed by the intermediate transfer member and the secondary transfer member;
- and
- conveying the recording medium at the first speed for a predetermined time after the recording medium reaches the transfer portion.
