Image forming apparatus
View Patent ↗An image forming apparatus includes an image forming unit that forms an image to be formed on a recording medium. The image formed by the image forming unit has a size larger than a size of the recording medium that is transported, the image forming unit causing the image to adhere to the entire area of the recording medium. A width of the image in a direction substantially orthogonal to a transporting direction of the recording medium increases from a front end toward a rear end of the recording medium in the transporting direction of the recording medium.
1. An image forming apparatus comprising:
an image forming unit that forms an image to be formed on a recording medium,
wherein the image formed by the image forming unit has a size larger than a size of the recording medium that is transported, the image forming unit causing the image to adhere to the entire area of the recording medium,
wherein a width of the image in a direction substantially orthogonal to a transporting direction of the recording medium increases from a front end toward a rear end of the recording medium in the transporting direction of the recording medium.
2. The image forming apparatus according to claim 1 , wherein the image forming unit includes
an image carrier that includes a photoconductor layer,
a charging device that charges a surface of the image carrier,
an exposure device that forms a latent image based on a difference in electrostatic potential by irradiating the charged image carrier with image light,
a developing device that forms a toner image by transferring toner to the latent image, and
a transfer device that transfers the toner image onto the recording medium directly or through an intermediate transfer body,
wherein the exposure device irradiates the image carrier with the image light in an area such that a width of the toner image at a rear end in the transporting direction of the recording medium is larger than a width of the toner image at a front end in the transporting direction of the recording medium when the toner image is transferred onto the recording medium.
3. The image forming apparatus according to claim 1 , wherein the difference between the width of the image in the direction substantially orthogonal to the transporting direction of the recording medium and a width of the recording medium in the direction substantially orthogonal to the transporting direction of the recording medium is set so as to decrease as a basis weight of the recording medium increases.
4. The image forming apparatus according to claim 2 , wherein the difference between the width of the image in the direction substantially orthogonal to the transporting direction of the recording medium and a width of the recording medium in the direction substantially orthogonal to the transporting direction of the recording medium is set so as to decrease as a basis weight of the recording medium increases.
5. The image forming apparatus according to claim 1 , wherein the difference between the width of the image in the direction substantially orthogonal to the transporting direction of the recording medium and a width of the recording medium in the direction substantially orthogonal to the transporting direction of the recording medium is changed in accordance with a dimension of the recording medium in a width direction.
6. The image forming apparatus according to claim 2 , wherein the difference between the width of the image in the direction substantially orthogonal to the transporting direction of the recording medium and a width of the recording medium in the direction substantially orthogonal to the transporting direction of the recording medium is changed in accordance with a dimension of the recording medium in a width direction.
7. The image forming apparatus according to claim 3 , wherein the difference between the width of the image in the direction substantially orthogonal to the transporting direction of the recording medium and a width of the recording medium in the direction substantially orthogonal to the transporting direction of the recording medium is changed in accordance with a dimension of the recording medium in a width direction.
8. The image forming apparatus according to claim 4 , wherein the difference between the width of the image in the direction substantially orthogonal to the transporting direction of the recording medium and a width of the recording medium in the direction substantially orthogonal to the transporting direction of the recording medium is changed in accordance with a dimension of the recording medium in a width direction.
