Image forming apparatus

摘要

An image forming apparatus includes: an intermediary transfer member (belt); first and second accommodating portions; a detecting member; an executing portion for executing a removing operation for removing the toner image transferred on the belt by once interrupting a continuous job for continuously forming an image on the recording material fed from the first accommodating portion when discrimination that there is no recording material in the first accommodating portion is made on the basis of a detection result of the detecting member during the continuous job and then for executing a switching operation for resuming the continuous job by feeding the recording material from the second accommodating portion; and a setting portion for setting a moving speed of the belt during execution of the removing operation so as to be higher than a moving speed of the belt when the toner image is transferred onto the recording material.

1. An image forming apparatus comprising:
a movable intermediary transfer member onto which a toner image to be transferred onto a recording material is once transferred; first and second accommodating portions for accommodating recording materials; a detecting member for detecting a recording material in said first accommodating portion; an executing portion for executing a removing operation for removing the toner image transferred on said intermediary transfer member by once interrupting a continuous job for continuously forming an image on recording materials fed from said first accommodating portion when a discrimination that there is no recording material in said first accommodating portion is made on the basis of a detection result of said detecting member during the continuous job and then for executing a switching operation for resuming the continuous job by feeding a recording material from said second accommodating portion; and a setting portion for setting a moving speed of said intermediary transfer member during execution of the removing operation so as to be higher than a moving speed of said intermediary transfer member when the toner image is transferred onto the recording material.
