An image forming apparatus includes an image carrier, a transfer member provided at a position at which the transfer member can be pressed against the image carrier, a detection device for detecting a toner attachment amount of the toner image formed on the image carrier, an avoidance judging section for judging whether or not avoidance of a pressed region should be performed when a toner image for image formation is formed on the image carrier, the pressed region serving as a region located on the image carrier and being pressed against the transfer member from the end of a previous image forming operation to the start of a present image forming operation, and an avoidance continuation judging section for judging the necessity for continuation of the avoidance by being operated when it is judged as avoidance by the avoidance judging section.

Image forming apparatus

An image-forming apparatus comprises an intermediate transfer member having a hard release layer on the surface that receives a primarily transferred toner image from a latent image-supporting member on the hard release layer and secondarily transfers the toner image to an image-receiving medium, wherein,

Image-forming apparatus equipped with specified intermediate transfer member

An image forming apparatus which is free from occurrence of image noise due to the bleed phenomenon even without providing any contact-and-separation mechanism for the transfer member includes a control device which counts stop time elapsing from a stop to a restart of the image carrier, calculates an avoidance sheet count corresponding to the stop time at a restart of the image carrier, and makes a toner image carried on only part of the image carrier that has been out of the nip against the transfer member during the stop of the image carrier until the avoidance sheet count is reached after the restart of the image carrier.

Image-forming apparatus equipped with intermediate transfer member

An image-forming apparatus that is provided with an intermediate transfer member that has a hard releasing layer formed on the surface thereof, supports a toner image primary-transferred onto the hard releasing layer from a latent-image supporting member, and secondary-transfers the supported toner image onto an image-receiving medium, and a cleaning blade that is arranged in contact with the intermediate transfer member, and removes residual toner from the hard releasing layer of the intermediate transfer member, wherein the cleaning blade has an impact resilience in the range from 20 to 50% at 20&#xb0; C.

Image-forming apparatus

An image-forming apparatus, equipped with an intermediate transfer memberhaving a surface layer that holds a toner image primary-transferred from a latent image-supporting member temporarily on the surface layer and allows secondary transfer of the toner image held thereon to an image receiving medium,
