Image forming apparatus

Abstract

PROBLEM TO BE SOLVED: To provide an image forming apparatus that reduces variations in time when an envelope whose thickness or rigidity changes in a conveyance direction reaches a registration roller, and enables stable productivity.SOLUTION: The image forming apparatus 1 includes: a registration roller; a conveyance roller; a conveyance part driving source 231; a conveyance sensor 285; an envelope information storage 810 for storing envelope information; and a conveyance acceleration/deceleration speed controller 803 for controlling an acceleration/deceleration speed of a conveyance speed using the conveyance roller of a body of the envelope 100E, on the basis of a conveyance position of the envelope 100E and the envelope information stored in the envelope information storage 810, and controlling the conveyance part driving source 231 so that the registration roller 37 conveys the envelope 100E for a conveyance fixed time from the start of conveying the envelope 100E to the registration roller 37.
【課題】本発明は、厚さや腰が搬送方向に変化する封筒のレジストローラへの到達タイミングのばらつきを減少することができ、生産性を安定化することができる画像形成装置を提供する。 【解決手段】画像形成装置1において、レジストローラと、搬送ローラと、搬送部駆動源231と、搬送センサ285と、封筒情報を格納する封筒情報格納部810と、封筒100Eの搬送位置及び封筒情報格納部810に格納された封筒情報に基づき、封筒100Eの本体の搬送ローラを用いた搬送速度の加減速度を制御し、封筒100Eの搬送開始からレジストローラ37に至る一定搬送時間においてレジストローラ37に封筒100Eを搬送するように搬送部駆動源231を制御する搬送加減速度制御部803とを備える。 【選択図】図4
