IMAGE FORMING APPARATUS
First Claim
1. An image forming apparatus comprising:
- a feeding member configured to feed a recording material stacked on a stacking unit;
a conveying member configured to convey the recording material fed by the feeding member;
a separation member configured to separate a plurality of recording materials so that one recording material is conveyed in a case where the plurality of recording materials is fed from the stacking unit by the feeding member;
a detecting unit disposed on a downstream side of the conveying member in a conveyance direction of the recording material, and configured to detect the recording material;
a controller configured to control the feeding member and the conveying member; and
an image forming unit configured form an image on the recording material conveyed by the conveying member,wherein, in a case where a type of the recording material is a first type, the controller controls the feeding member to feed the recording material stacked on the stacking unit at a first speed, and the controller controls the conveying member to change a speed of the recording material from the first speed to a second speed that is faster than the first speed before the detecting unit detects the recording material, andwherein, in a case where the type of the recording material is a second type that is different from the first type, the controller controls the feeding member to feed the recording material stacked on the stacking unit at a third speed that is different from the first speed, and the controller controls the conveying member to change the speed of the recording material from the third speed to a fourth speed that is different from the third speed after the detecting unit detects the recording material.

Abstract
An image forming apparatus includes a feeding member, a conveying member, and a detecting unit. The feeding member feeds a recording material stacked on a stacking unit. The conveying member convey the fed recording material. The detecting unit detect the conveyed recording material. Where the recording material is a first type, the feeding member feeds the stacked recording material at a first speed, and the conveying member changes the first speed to a second speed that is faster than the first speed before the detecting unit detects the recording material. Where the recording material is a second type that is different from the first type, the feeding member feeds the stacked recording material a third speed that is different from the first speed, and the conveying member changes the third speed to a fourth speed that is different from the third speed after the detecting unit detects the recording material.
