I have created a custom module and in the admin  New/Edit form I added the image field but when I submit the form with uploading image, it won't show the image in save controller.

I used to add below code to add image field in admin from:

    $fieldset->addField(
            'image',
            'image',
            array(
                'label' => __('Image'),
                'name'  => 'image',
                'class' =>'admin__control-image',
        )
        );

also in my form, I added the multipart form data as below: 

    protected function _prepareForm()
    {
        /** @var \Magento\Framework\Data\Form $form */
        $form = $this->_formFactory->create(
            ['data' => ['id' => 'edit_form', 'action' => $this->getData('action'), 'method' => 'post' , 'enctype' => 'multipart/form-data']]
        );
        $form->setUseContainer(true);
        $this->setForm($form);
        return parent::_prepareForm();
    }

How to get rid of this issue?

Thanks in advance!
